planar optical waveguide based dimethylamine sensor with Cresol Red tio 2 composite thin film
Journal of The Optical Society of America B-optical Physics, 2020Co-Authors: Nuerguli Kari, Lili Wang, Patima Nizamidin, Shawket Abliz, Abliz YimitAbstract:A planar optical glass-slide-based dimethylamine (DMA) sensor was fabricated with composite thin film of Cresol Red and titanium dioxide as the sensing layer and tin-diffused planar glass slide as the substrate. The UV-visible spectrum before and after analyte exposure was investigated to detect the color transformation of sensing layer and to select a laser light source wavelength (532 nm). DMA detection response along with time were performed on an optical waveguide system at room temperature. Experimental results show that this sensing film had not only fast response (6 s) but also rapid recovery (21 s) (${0.004}\;{{\rm mg/m}^3}$0.004mg/m3). Besides, detection is available for DMA solution as low as ${0.0008}\;{{\rm mg/m}^3}$0.0008mg/m3 concentration with signal-to-noise ratio (S/N) 5.29. The sensing film is stable for one month at ambient temperature, and the response reaction is reversible.

Biotransformation studies of Cresol Red by Absidia spinosa M15.
Journal of Environmental Management, 2016Co-Authors: Risky Ayu Kristanti, Meor Mohd Fikri Ahmad Zubir, Tony HadibarataAbstract:Abstract Cresol Red, a commercial dye that used widely to color nylon, wool, cotton, and polyacrylonitrile-modified nylon in the massive textile manufacture is toxic recalcitrant. Absidia spinosa M15, a novel fungal strain isolated from a tropical rain forest, was found to decolorize Cresol Red 65% within 30 d under agitation condition. UV–Vis spectroscopy, TLC analysis and mass spectra of samples after decolorization process in culture medium confirmed final decolorization of Cresol Red. Two metabolites were identified in the treated medium: benzeneacetic acid (t R 9.6 min and m/z 136) and benzoic acid (t R 5.7 min and m/z 122). Laccase showed the significant activity (133.8 U/L) in biomass obtained at the end of experiment demonstrates role of the enzyme in the decolorization process.

ORIGINAL PAPER Mechanism of triphenylmethane Cresol Red degradation
2016Co-Authors: Trichoderma Harzianum M, Tony Hadibarata, Meor Mohd Fikri Ahmad Zubir, Nurafifah Mohd Nor, Zainab Mat LazimAbstract:(TPM) class of dyes which are potentially carcinogenic or mutagenic. However, very few studies on biodegradation of Cresol Red were investigated as compaRed to other type dyes such as azo and anthraquinone dye. The aim of this work is to evaluate triphenylmethane dye Cresol Red degradation by fungal strain isolated from the decayed wood in Johor Bahru, Malaysia. Detailed taxonomic stud-ies identified the organisms as Trichoderma species and designated as strain Trichoderma harzianum M06. In this study, Cresol Red was decolorized up to 88 % within 30 days under agitation condition by Trichoderma harzianum M06. Data analysis revealed that a pH value of 3 yielded a highest degradation rate among pH concentrations (73 %), salinity concentrations of 100 g/L (73 %), and a volume of 0.1 mL of Tween 80 (79 %). Induction in the enzyme activities of manganese peroxidase, lignin peroxidase, laccase, 1,2- and 2,3-dioxygenase indicates their involve-ment in Cresol Red removal. Various analytical studies such as Thin-Layer Chromatography (TLC), UV–Vis spectrophotometer, and Gas chromatography mass spec-trometry (GC–MS) confirmed the biotransformation of Cresol Red by the fungus. Two metabolites were identified in the treated medium: 2,4-dihydroxybenzoic acid (tR 7.3 min and m/z 355) and 2-hydroxybenzoic acid (tR 8.6 min and m/z 267). Based on these products, a probable pathway has been proposed for the degradation of Cresol Red by Trichoderma harzianum M06

REMOVAL OF Cresol Red AND REACTIVE BLACK 5 DYES BY USING SPENT TEA LEAVES AND SUGARCANE BAGGASE POWDER
Jurnal Teknologi, 2015Co-Authors: Zainab Mat Lazim, Tony Hadibarata, Nur Syazlin Zulkifli, Zulkifli YusopAbstract:Textile wastewater will be the major problems regarding the chemical pollution due to the color effluent that the textile industrial produced. The synthetic dye that will be found in another manufacturing which was can damage not only towards the environment but also a human health. The purpose of this research was to identify the solution for treating the wastewater. One of the pre-treatment to treat the wastewater was by physical method. The method that will be used was adsorption process by using synthetic dyes (Cresol Red and Reactive Black 5) and synthetic water (distilled water). This research will be conducted to determine which agricultural wastes (Spent Tea Leaves and Bagasse Powder) react with the synthetic dyes. Experiments were carried out with agricultural waste sample and the synthetic dyes at 1000ppm concentration. 50ml of both dyes will then mix with the 5 g of agricultural waste for 24 hours to show how the agricultural waste was effective adsorption to the removal of synthetic dyes. The adsorption of Cresol Red and Reactive Black 5 were measuRed and the most effective adsorption was spent tea leaves on Cresol Red dyes which was the percentage rate removal of adsorption was 68.55 %. The results indicate the higher removal rate shows the more adsorption capacity of the adsorbent.

Structural, Optical, and pH-Stimulus Response Properties of Cresol Red Immobilized Nanocomposite Silica Films Derived by a Sol–Gel Process Employing Different Synthetic Routes
Industrial & Engineering Chemistry Research, 2014Co-Authors: Shobhit Singh Chauhan, R. V. Jasra, A. L. SharmaAbstract:Formation of Cresol Red dye immobilized silica films derived by conventional as well as CTAB and P123 templated sol–gel is discussed. Comparative structural, textural, and optical properties of films derived by these three different methodologies were determined using analytical instrumental techniques like X-ray Diffraction (XRD), Atomic Force Microscope (AFM), Scanning Electron Microscope (SEM), surface area, and porosity measurements. Optical and pH sensing response properties of films were monitoRed by visible spectrophotometer. An attempt is made to demonstrate how incorporation of dyes affects the structure and interactions in films formed by different described methods leading to functional benefits in pH stimuli response behavior.
