A new adsorption process for As(V) ion removal from an aqueous solution was studied using molybdate impregnated chitosan beads (MICB). Arsenate ions were strongly adsorbed in the pH range from 2 to 4 with a minimum release of molybdate ions. The sorption mechanism is a complexation between arsenate ions and molybdate ions. Even at low equilibrium concentration, the sorption capacity is high, and allows...
