Anticorrosion Behaviour of Rhizophora mangle L. Bark-Extract on Concrete Steel-Rebar in Saline/Marine Simulating-Environment.
The Scientific World Journal, 2019Co-Authors: Joshua Olusegun Okeniyi, Esther T. Akinlabi, Jacob Olumuyiwa Ikotun, Elizabeth Toyin OkeniyiAbstract:This paper investigates anticorrosion behaviour of the bark-extract from Rhizophora mangle L. on steel-rebar in concrete slabs in 3.5% NaCl medium of immersion (for simulating saline/marine environment). Corrosion-rate, corrosion-current, and corrosion-potential were measured from the NaCl-immersed steel-reinforced concrete cast with admixture of different plant-extract concentrations and from positive control concrete immersed in distilled water. Analyses indicate excellent mathematical-correlation between the corrosion-rate, concentration of the bark-extract admixture, and electrochemical noise-resistance (ratio of the corrosion-potential standard deviation to that of corrosion-current). The 0.4667% Rhizophora mangle L. bark-extract admixture exhibited optimal corrosion-inhibition performance, η = 99.08±0.11% (experimental) or η = 97.89±0.24% (correlation), which outperformed the positive control specimens, experimentally. Both experimental and correlated results followed Langmuir adsorption isotherm which suggests prevalent physisorption mechanism by the plant-extract on the reinforcing-steel corrosion-protection. These findings support Rhizophora mangle L. bark-extract suitability for corrosion-protection of steel-rebar in concrete structure designed for immersion in the saline/marine environmental medium.

Biochemical characterization data from Fourier transform infra-red spectroscopy analyses of Rhizophora mangle L. bark-extract
Chemical Data Collections, 2019Co-Authors: Joshua Olusegun Okeniyi, Esther T. Akinlabi, Stephen A. Akinlabi, Elizabeth Toyin OkeniyiAbstract:Abstract This article presents biochemical characterization data, of organic functional groups and 3-D optimized structures of identified organic chemicals, from the Fourier transform infra-red (FT-IR) spectroscopy analyses of Rhizophora mangle L. bark-extract. Spectral plot from FT-IR spectroscopy instrumentation application to the Rhizophora mangle L. bark-extract, which includes numerical data of adsorbed frequencies for indicating fingerprints/vibration modes of organic functional groups, is supplied in the paper. The obtained spectrum was also rendered to the computer-based Euclidean Search® of the Fluka Library® reference database, for obtaining hit-list of organic chemical compounds constituted in the bark-extract. Adsorbed functional groups from the FT-IR spectroscopy, including N H, C N, C N, O P(=O)(H O) and S-containing ligands, are corroborated by the chemical compounds identified by the computer-based hit-list. These data of biochemical constituent characterizations are useful for gaining insights into the prospects of using bark-extract from Rhizophora mangle L. natural-plant for corrosion-protection of metallic materials in aggressive service-environments.

Rhizophora mangle L. LEAF BIOCHEMICAL CHARACTERIZATION: NATURAL-GREEN TOTAL-CORROSION INHIBITION PROSPECT ON CONCRETE STEEL-REINFORCEMENT IN 3.5% NaCl
Jurnal Teknologi, 2018Co-Authors: Joshua Olusegun Okeniyi, Esther T. Akinlabi, Stephen A. Akinlabi, Elizabeth Toyin Okeniyi, Jacob Olumuyiwa Ikotun, Ojewumi Modupe ElizabethAbstract:Effective corrosion-protection by plant-extract on metals, in aggressive service-environment, is dependent on the biochemical constituents of which the natural plant is made-up. This paper investigates biochemical characterization of inorganic and organic constituents of Rhizophora mangle L. leaf for gaining insight on its steel-reinforcement corrosion mitigating prospect in NaCl-immersed concretes. For the study, atomic absorption spectroscopy (AAS), Fourier transform infrared spectroscopy (FT-IR) and phytochemical screening analyses were employed. Total-corrosion effect was also studied from steel-reinforced concrete samples, having different concentrations of the leaf-extract as admixture, and which were immersed in 3.5% NaCl (simulating saline/marine environment). Results, by AAS, showed that Rhizophora mangle L. leaf inorganic constituents were highest in iron, Fe = 10,316.17 μg/g and lowest in cadmium, Cd = 6.2019 μg/g but has neither lead (Pb) nor chromium (Cr). Also, organic constituents, by FT-IR, indicated extract from the leaf constitutes aromatic chained compounds rich in π-electrons as well as sulphur, nitrogen and oxygen-bearing ligands to which iron (steel-rebar) exhibits coordinate affinity. Phytochemical characterization showed that the leaf-extract contains alkaloids, tannins, phlobatannins, saponins, steroids and glycosides. Corrosion-inhibiting prospect testing, using the leaf-extract, indicated reduced steel-reinforcement total-corrosion effects that correlated with the extract admixture concentrations employed in the 3.5% NaCl-immersed steel-reinforced concretes.

Anticorrosion and Adsorption Mechanism of Rhizophora mangle L. Leaf-Extract on Steel-Reinforcement in 3.5% NaCl-Immersed Concrete
Proceedings of the 3rd Pan American Materials Congress, 2017Co-Authors: Joshua Olusegun Okeniyi, Cleophas Akintoye Loto, Olugbenga Adeshola Omotosho, Abimbola Patricia Idowu PopoolaAbstract:This paper studies anticorrosion and adsorption mechanism of Rhizophora mangle L. leaf-extract on steel-reinforcement in concrete immersed in 3.5% NaCl test-environment. Open circuit potential, macrocell current and corrosion rate measurements were obtained from steel-reinforced concrete samples, into which different concentrations of the leaf-extract was admixed during casting, and which were immersed in the saline/marine simulating-environment. Corrosion noise resistance was modelled as the ratio of standard deviation of the corrosion potential to the standard deviation of the corrosion current. Analyses of these test-results showed that the corrosion rate from linear polarization resistance exhibited very good correlation with the noise resistance model for the leaf-extract concentrations studied. Further analyses identified Rhizophora mangle L. leaf-extract concentration with excellent corrosion inhibition efficiency performance on steel-reinforcement. Also data of anticorrosion performance followed the Langmuir adsorption isotherm model, which indicated physisorption as the prevalent corrosion-protection mechanism by the Rhizophora mangle L. leaf-extract on steel-rebar in concrete immersed in the 3.5% NaCl, simulating saline/marine environment.

evaluation and analyses of Rhizophora mangle l leaf extract corrosion mechanism on reinforcing steel in concrete immersed in industrial microbial simulating environment
Journal of Applied Sciences, 2015Co-Authors: Joshua Olusegun Okeniyi, C A Loto, A. P. I. PopoolaAbstract:Test-data from electrochemical monitoring methods were obtained from Rhizophora mangle L. leaf-extract admixed steel-reinforced concretes for detailing mechanism of the extract on steel-rebar corrosion in 0.5 M H2SO4 (simulating industrial/microbial environment). These electrochemical test-measurements, including corrosion potential, corrosion current and corrosion rate, were subjected to the analyses of probability distributions as per ASTM G16-95 R05 through the Kolmogorov-Smirnov goodness-of-fit test-statistics. Results showed that corrosion rate exhibited correlations with function of the natural plant-extract concentration and compact series of the inverse electrochemical noise resistance; the ratio of standard deviations of corrosion potential and corrosion current. Both the experimental and the correlated-prediction model identified Rhizophora mangle L. leaf-extract admixture concentrations that exhibited inhibition efficiency performance of η>70% on steel-rebar corrosion in the acidic test-medium. The adsorption isotherm modelling of the experimental and the predicted electrochemical test-results exhibited good agreements by following the Langmuir and Flory-Huggins isotherm fittings. In addition, the study identified physisorption as the prevalent corrosion-protection mechanism of the steel-rebar by the plant extract through both of the experimental and the correlated-prediction models of adsorption isotherm analyses.

Performance of Rhizophora mangle L. Leaf-Extract and Sodium Dichromate Synergies on Steel-Reinforcement Corrosion in 0.5 M H 2 SO 4 -Immersed Concrete
Corrosion, 2015Co-Authors: Joshua Olusegun Okeniyi, Cleophas Akintoye Loto, Abimbola Patricia Idowu Popoola, Olugbenga Adeshola OmotoshoAbstract:This paper investigates performance of different synergistic combinations of Rhizophora mangle L leaf-extract and sodium dichromate (Na2Cr2O7) admixtures on the corrosion of steel-reinforcement in 0.5 M H2SO4-immersed concrete. Steel-reinforcement corrosion, in concrete slabs partially-immersed in the microbial/industrial simulating test-environment, were assessed using non-destructive electrochemical measurements of corrosion rate (CR) and open circuit potential (OCP). Probability distribution function (pdf) analyses, as prescribed by ASTM G16-95 R04, of the scatter of corrosion test-data showed that while datasets of OCP distributed like the Normal, the Gumbel and Weibull pdf's, the datasets of CR were best fitted by the Weibull pdf. Results identified 6 g Rhizophora mangle L leaf-extract + 2 g Na2Cr2O7 synergistic admixture with both optimal inhibition efficiency, η = 90.12, and synergistic parameter that indicated excellent synergistic interaction of the plant-extract with Na2Cr2O7 chemical. That this synergistic admixture out-performed the also effective Na2Cr2O7 admixtures in the study suggests suitability of Rhizophora mangle L leaf-extract as eco-friendly replacement of toxic Na2Cr2O7 inhibitor in H2SO4-immersed steel-reinforced concrete. This is potent with the advantage of reducing environmental effect from lower Na2Cr2O7 usage for controlling corrosion in steel-reinforced concretes for the microbial/industrial environment. © 2015 by Nace International.

TMS2015 Supplemental Proceedings, 2015Co-Authors: Joshua Olusegun Okeniyi, Cleophas Akintoye Loto, Abimbola Patricia Idowu PopoolaAbstract:In this paper, electrochemical test-data were obtained from 0.5 M H2SO4-immersed steel-reinforced concrete admixed with different Rhizophora mangle L bark-extract concentrations and subjected to modelling analyses for studying corrosion-inhibition effectiveness. For this, macrocell current from zero-resistance ammeter and corrosion-rate from linear-polarization resistance instruments were respectively subjected to total-corrosion modelling as per ASTM G109-99a and statistical-distribution modelling as per ASTM G16-95 R04. Further analyses of these modelled test-results showed that the corrosion-rate correlated excellently (R = 95.04%, Nash-Sutcliffe efficiency = 90.33%, p-value = 0.037) with function of the bark-extract concentration and the total-corrosion from the steel-reinforced concrete samples. In agreements, both experimental and correlation fitting models identified 0.167% Rhizophora mangle L bark-extract with good corrosion-inhibition efficiency, η = 73.30% (experimental) or η = 60.81% (correlation prediction). These bare implications on macrocell technique usage for complimenting identification of admixture concentration for effective corrosion-inhibition of concrete steel-rebar in the microbial/industrial simulating-environment studied

The effects of condensed tannins derived from senescing Rhizophora mangle leaves on carbon, nitrogen and phosphorus mineralization in a Distichlis spicata salt marsh soil
Plant and Soil, 2018Co-Authors: Qiu Fang Zhang, Hendrikus J. LaanbroekAbstract:Background and aims Due to global warming, it is to be expected that mangroves will move north- and southwards and enter salt marshes, which will then be enriched with mangrove-derived organic compounds. Little is known about the effects that tannins, which are abundantly present in leaf litter of Rhizophora mangle, will have on the biogeochemical cycles in salt marsh soils.

Tide as Steering Factor in Structuring Archaeal and Bacterial Ammonia-Oxidizing Communities in Mangrove Forest Soils Dominated by Avicennia germinans and Rhizophora mangle.
Microbial Ecology, 2017Co-Authors: Magalí S. Marcos, Anthony Diego Muller Barboza, Rosalinde M. Keijzer, Hendrikus J. LaanbroekAbstract:Mangrove species are adapted to grow at specific zones in a tidal gradient. Here we tested the hypothesis that the archaeal and bacterial ammonia-oxidizing microbial communities differ in soils dominated by the mangrove species Avicennia germinans and Rhizophora mangle. Two of the sampling locations were tidal locations, while the other location was impounded. Differences in the community compositions of ammonia-oxidizing archaea (AOA) and bacteria (AOB) were analyzed by denaturing gradient gel electrophoresis (DGGE) of amoA genes and by MiSeq 16S rRNA gene-sequencing. The abundances of AOA and AOB were established by quantitative PCR of amoA genes. In addition, we analyzed the total microbial community composition based on 16S rRNA genes and explored the influence of soil physicochemical properties underneath Avicennia germinans and Rhizophora mangle on microbial communities. AOA were always more abundant than AOB, but the effect of mangrove species on total numbers of ammonia oxidizers was location-specific. The microbial communities including the ammonia oxidizers in soils associated with A. germinans and R. mangle differed only at the tidal locations. In conclusion, potential site-specific effects of mangrove species on soil microbial communities including those of the AOA and AOB are apparently overruled by the absence or presence of tide.
