Kinetic study on removal of heavy metal ions from aqueous solution by using soil

In the present study, the feasibility of soil used as a low-cost adsorbent for the removal of Cu2+, Zn2+, and Pb2+ ions from aqueous solution was investigated. The kinetics for adsorption of the heavy metal ions from aqueous solution by soil was examined under batch mode. The influence of the con...
