| Abstract: | Adsorption kinetics for removal of arsenic was carried out by red mud and its mixtures with haematite, china clay and fly ash besides china clay-fly ash at: adsorbate conc., 5.0 mg1-1; particle size of adsorbent, <53 μm; agitation rate, 220 rpm; pH, 8.0; and temp., 30, 40 & 50°C. Data fit into Lagergren equation and adsorption follows first order reaction kinetics. As(III) removal by adsorbents is diffusion controlled. A low value of activation energy indicates flat nature of energy barrier. |
