The present work has been envisaged to develop an efficient process for adsorptive decontamination of Brilliant green (BG) dye from waste water at room temperature. In recent past, various natural as well as advanced materials and composites have been reported to remove dyes from water. But these materials have certain limitations like time consumption, lower adsorption capacity and residual toxicity etc. To overcome these limitations, zinc peroxide-charcoal composite (ZnO2-C) has been synthesized by wet chemical route. The proposed composite efficiently decontaminates BG from waste water within 25 minute in wide pH range (2-9). The spectral and microscopic studies have been done for ZnO2-C composite before and after adsorption of BG to know the adsorption behavior of proposed material. Various parameters like pH, adsorbent dose, contact time and dye concentration were optimized by the batch sorption experiment to determine maximum adsorption capacity of ZnO2-C. The adsorption capacity of the composite was found to be 156.1 mg g-1 which is better than several other adsorbents cited in literature in recent past. The experimental adsorption data follows second order kinetics and Freundlich adsorption isotherm.
