Effects of pH, adsorbent dose, adsorbate concentration and contact time were studied. The concentration of As(III) and As(V) was determined spectrophotometrically by molybdenum blue method. Maximum adsorption was observed at pH 8 and pH 5 for As(III) and As(V) and at optimum contact time of 4 hrs and 3 hrs, respectively at an initial concentration of 5 mg/L. Maximum adsorption capacity (qmax) value of FeCSCB was found to be 25 mg/g and 70 mg/g for the adsorption of As(III) and As(V), respectively. Kinetics and isotherms modeling studies demonstrated that the experimental data best fitted with pseudo second order kinetic model and Langmuir isotherm model, respectively. This study revealed that FeCSCB can be used as an efficient, ecofriendly and economic material for the adsorptive removal of As(III) and As(V) from aqueous system.
