  • simultaneous removal of cr vi and Amido Black 10B ab10B from aqueous solutions using quaternized chitosan coated bentonite
    International Journal of Biological Macromolecules, 2016
    Co-Authors: Pan Hu, Jing Wang, Ruihua Huang

    Abstract:

    Abstract In this study, simultaneous removal of Cr(VI) and Amido Black 10B (AB10B) using quaternized chitosan coated bentonite was investigated by a batch method. The factors affecting adsorption process such as pH, adsorbent dosage, contact time and initial concentration and the interaction of two components in binary solutions have been studied. The results showed that the antagonism effect existed between Cr(VI) and AB10B in binary systems. The equilibrium time for Cr(VI) adsorption was less than the one for AB10B adsorption. The maximum adsorption capacities of the modified bentonite, according to the Langmuir isotherm model were 847.5 mg/g for AB10B and 66.6 mg/g for Cr(VI) at 298 K. The experimental results demonstrated that both Cr(VI) and AB10B were well described by the pseudo-second-order model. Thermodynamic study depicted that the adsorption of Cr(VI) and AB10B onto the modified bentonite was both spontaneous. The adsorption for Cr(VI) was exothermic while the one for AB10B was endoth- ermic in nature.

  • adsorption of Amido Black 10B from aqueous solutions onto zr iv surface immobilized cross linked chitosan bentonite composite
    Applied Surface Science, 2016
    Co-Authors: Lujie Zhang, Pan Hu, Jing Wang, Ruihua Huang

    Abstract:

    Abstract Zr(IV) surface-immobilized cross-linked chitosan/bentonite composite was synthesized by immersing cross-linked chitosan/bentonite composite in zirconium oxychloride solution, and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, Scanning electron microscopy techniques. The adsorption of an anionic dye, Amido Black 10B, from aqueous solution by Zr(IV) loaded cross-linked chitosan/bentonite composite was investigated as a function of loading amount of Zr(IV), adsorbent dosage, pH value of initial dye solution, and ionic strength. The removal of Amido Black 10B increased with an increase in loading amount of Zr(IV) and adsorbent dosage, but decreased with an increase in pH or ionic strength. The adsorption of AB10B onto Zr(IV) loaded cross-linked chitosan/bentonite composite was favored at lower pH values and higher temperatures. The Langmuir isotherm model fitted well with the equilibrium adsorption isotherm data and the maximum monolayer adsorption capacity was 418.4 mg/g at natural pH value and 298 K. The pseudo-second-order kinetic model well described the adsorption process of Amido Black 10B onto Zr(IV) loaded cross-linked chitosan/bentonite composite. The possible mechanisms controlling Amido Black 10B adsorption included hydrogen bonding and electrostatic interactions.

  • construction of biocooh g c3n4 composite photocatalyst and its enhanced visible light photocatalytic degradation of Amido Black 10B
    Separation and Purification Technology, 2019
    Co-Authors: Xinyi Zhang, Xiuwen Cheng, Huixuan Zhang, Qingfeng Cheng

    Abstract:

    Abstract The application of semiconductor photocatalysts in wastewater treatment has received increasingly attentions because of its potential utilization of solar energy. In this study, a novel visible-light-driven (VLD) BiOCOOH/g-C3N4 composite photocatalyst was successful synthesized by a facile hydrothermal method. Afterwards, physicochemical properties of the resulting samples were investigated through X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) surface areas, UV–visible diffuse reflectance spectroscopy (UV–vis DRS), transient photocurrent density, Mott-Schottky (M−S) and electrochemical impedance spectroscopy (EIS) measurement. Furthermore, the visible light photocatalytic (PC) performance was evaluated through the degradation of Amido Black 10B dye. All results indicated that the combination of g-C3N4 and BiOCOOH could exhibited greatly visible light absorbance and photo-generated charge separation efficiency, thereby resulting in the enhanced PC performance of BiOCOOH/g-C3N4 composite photocatalyst. The optimal Bi/C molar rate in BiOCOOH/g-C3N4 composite was determined to be 1/1, and the corresponding photodegradation rate for Amido Black 10B was 0.01794 min−1, which was nearly 2.19 and 5.73 folds higher than that of pure g-C3N4 and BiOCOOH. The possible mechanism of the PC reaction was also discussed in detail. Furthermore, BiOCOOH/g-C3N4 composite photocatalyst performed good reusability and stability even after four recycle utilization.

  • Construction of Bi2O3/g-C3N4 composite photocatalyst and its enhanced visible light photocatalytic performance and mechanism

    Co-Authors: Xinyi Zhang, Huixuan Zhang, Qingfeng Cheng, Bo Li, Xiuwen Cheng

    Abstract:

    Abstract To improve the photocatalytic (PC) performance of g-C 3 N 4 nano-material, a novel Z-scheme Bi 2 O 3 /g-C 3 N 4 composite photocatalyst was synthesized by heat treatment method. Subsequently, the morphologies, chemical structures, optical and photoelectrochemical (PECH) properties of as-obtained photocatalysts were investigated through X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) surface areas, UV–visible diffuse reflectance spectroscopy (UV–vis DRS), transient photocurrent density, Mott-Schottky (M-S) and electrochemical impedance spectroscopy (EIS) measurement. Furthermore, the PC efficiency was evaluated by degradation of Amido Black 10B dye. All results indicated that as-fabricated Bi 2 O 3 /g-C 3 N 4 photocatalytic system displayed superior PC performance under visible light illumination, which was mainly ascribed to the intense visible light absorbance and the migration of photo-generated carriers adopted a Z-scheme mechanism. Moreover, the degradation of Amido Black 10B for 3 wt.%Bi 2 O 3 /g-C 3 N 4 were about 1.41 and 1.42 times than that of pure g-C 3 N 4 and pure Bi 2 O 3 , respectively.
