Natural minerals are used to remove Arsenic (As) from aqueous solution in this study. The influence of suspension pH, temperature, agitation speed and arsenic dosage on arsenic removal is investigated in a series of batch adsorption experiments. In addition, empirical relationships are developed between % As (V) removal and adsorbent, adsorbate dose. Thermodynamic parameters are evaluated from temperature experiments. The kinetic is found to be pseudo second order in nature. The negative value of free energy change indicates the spontaneity of adsorption process. The adsorption of As (V) on natural minerals is found to be pore diffusion controlled in addition to surface adsorption. Source
