Abstract
Khangar has been used for the removal of As(III) ions from aqueous solution by adsorption process. Taguchi optimization method was used for optimization of process parameters like pH, adsorbent dose, metal ion concentration and contact time. L16 orthogonal array was used in designing the experiments. Statistical tools viz. signal to noise ratio and analysis of variance have been used at 95 % confidence level for all considered parameters. pH was found to be the most important parameter for removal of As(III) from aqueous solution. The optimum results were obtained at pH 7; adsorbent dose 0.7 g/50 mL; metal ion concentration 20 mg/L and contact time 120 min. SEM and FTIR studies of khangar before and after As(III) adsorption were made in order to understand the nature of adsorption. Comparison of adsorption on different adsorbents has also been included in the manuscript.
