Adsorption and Visible Light Photocatalytic Decolorization of Methyl Orange Using Innovative Chitosan Capped CdS Composite
Chitosan capped CdS (CdS/CS) composite was prepared by biomimetic synthesis method under mild conditions. Visible light photocatalytic decolorization of Methyl Orange (MO) was carried out by employing this innovative composite catalyst. Effect of catalyst amount, initial dye concentration, irradiation time, pH value, inorganic ions and reuse of the catalyst on decolorization was investigated. The kinetics of photocatalytic decolorization was found to follow a pseudo-first order reaction. UV-Vis spectra were analyzed to indicate that photocatalytic decolorization of the dye by CdS/CS composite catalyst was the synergistic effect of adsorption and degradation of dye actually. Results suggested that photocatalyst of CdS/CS is suitable for potential applications in organic waste removal from water by adsorption and photocatalysis.
