Abstract

The present study deals with the decolorization of C.I. Acid Red 88 (AR88) as a model contaminant from textile industry using sawdust as an adsorbent. The effects of initial AR88 concentration, adsorbent dosage, pH, contact time and stirring rate were studied in a batch mode. The variation of pH from 3 to 10 showed no considerable change in decolorization rate. The desired conditions for decolorization of 84.46\% were obtained to be 20 min of contact time, stirring rate of 400 rpm with 30 g L-1 of adsorbent. Freundlich, Redlich-Peterson and Langmuir adsorption models were used for the mathematical description of the equilibrium data and the equilibrium process confirmed well with all the models attaining correlation coefficients 0.970, 0.969 and 0.958, respectively.
