  The present study deals with the decolorization of CI Acid Red SR (ARAN as a model contaminant from textileindustry using sawdust as an adsorbent. The effects of initial AR88 concentration, adsorbent dosage, pH. c not acttime and ',riming rah: wcrg studied in a batch mode. The variation of pH from 3 to 10 showed no considerablechange in decolorization rate. The desired conditions for decolorization or 84.46% were obtained to be 20 minof contact time, stirring rate of 400 rpm with 30 g L."' of adsorbent. Freundlich, Redlich-Peterson and Langmuiradsorption models were used for the mathematical description of the equilibrium data and the equilibriumprocess confirmed well with all the models attaining corn:611On Csaciduittnts 0.970, 0.96V and 0.958.respectively. The results also revealed that the adsorption kinetics obeys pseudo-second order and it wasconcluded that intra-particle diffusion model is not the rate determining step. پرونده مقاله
