Abstract

The effect of inorganic ions and temperature on lead (Pb2+) adsorption was evaluated on 3 acidic soils : yellow-brown soil (YBS), latosol soil (LS), and lateritic red soil (LRS). The results showed that : the adsorption of Pb2+ was greater in the presence of SO42− than other ions; The increase of K+ and Ca2+ concentrations reduced the adsorption of Pb2+; Pb2+ adsorption was more pronounced in the yellow brown soil than in other soils. Pb2+ adsorption on soils was more favorable at 5–25 °C than at 35–45 °C
