| dc.description.abstract | A novel chitosan-indium sulphide (CS-In2S3) nanocomposite was synthesized by the method of co-precipitation. It was used in removing Victoria Blue (VB) dye from its aqueous solution. Firstly, chitosan and InCl3 were combined in solution phase followed by co-precipitation by the use of Na2S lead to the fabrication of the novel nanocomposite. The structure, surface morphology, constitution, and surface area of the synthesized composite were characterized by transmission electron microscopy (TEM), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Brunauer-Emmett-Teller (BET) analysis. The nearly spherical particles showed a large pore diameter of 170.384 Å. All the characterizations showed the agglomeration of In2S3 on the chitosan matrix. The fabricated nano-catalyst showed remarkable adsorption performance towards VB. The adsorption isotherms and kinetics of the sorption process were studied. The optimum catalyst dosage and dye concentration are obtained as 0.24 g/L and 100 mg/L. The BET isotherm, adsorption and kinetics studies shows that the nano-catalyst performs adsorptive removal of VB from its aqueous solution via monolayer chemisorption. The adsorption process was found to follow the pseudo-second order kinetics and was better fitted by the Langmuir adsorption isotherm than the Freundlich adsorption isotherm. The maximum adsorption capacity reached was 337.83 mg/g, and the pseudo-second order rate constant was determined to be 4.046*10-3 g.mg-1.min-1. | |
