Abstract
Heavy metals have an adverse effect on the environment and these effects can be seen visibly on food, soil, climate, plants etc. Therefore, removal of heavy metals from industrial wastewater is primarily of importance. In the present study, the removal of heavy metals (Cu2+, Pb2+) from the effluent from a textile industry was studied by adsorption technique using rice husk as adsorbent. The batch techniques was adopted under optimize condition of amount of adsorbent, time, and concentration using UV spectrophotometer. The concentration of heavy metals was measured before and after adsorption. The removal data were fitted into the Langmuir and freundlich isotherm equation. The value of their corresponding constant was determined. The pseudo-second-order rate equation as well as the micropore diffusion model described the kinetic data well. The study shows that about 90% of Cu2+ at 50mg/L and 65% of Pb2+ at 40mg/L was removed.The adsorption process was by a physical process (physiosorption).
