Adsorption and Statistical Analysis of Textile Effluent Contaminated with Congo red On Orange Peel

Abstract

In the present study we made an effort to deploy orange peel as adsorbent to remove Congo red dye from a synthetic media. Adsorption of Congo red dye was carried out using Response Surface Methodology (RSM).The influence of various factors such as adsorbent dosage, initial concentration of adsorbate and agitation time on adsorption was analyzed. A total no of 13 runs of experiments were conducted by using the detailed conditions which is designed by RSM based Box-Behnken Design. Contour plots and surface plots were analyzed to know the effect of factors. Activated orange peel could adsorb a maximum of 96.776% of congo red dye. The values observed in the experiment well agreed with the RSM predicted values .Activated orange peel seems to be better adsorbent and RSM could be a great tool undertake adsorption.: Congo Red Dye, Adsorption, Response Surface Methodology, Orange Peel, Box-Behnken Design.
