Abstract

In this paper, the leaching experiments are conducted with four kinds of environmental materials, polymer material (SAP), coal-based nutrient (HA), mineral adsorption material (FS) and mineral chemical material (SS), to explore the remediation effects of environmental materials on lead (Pb) and cadmium (Cd) contaminated soil. Electric conductivity (EC), pH value and Pb and Cd concentrations of leachates are measured to indicate the effects. The results show that the EC values of leachates reduce gradually in the four time leaching, and the pH values of leachates are insignificantly influenced by the environmental materials, meaning these environmental materials are suitable in farmland restoration. Environmental materials are effective in Pb and Cd contaminated soil remediation and could reduce heavy metal pollution of underground water. Among these materials, SS is the best material for Pb remediation, and the total content of Pb in leachates is 57.3% of CK after treated by SS; FS is the best for Cd, and compared with CK, the total Cd content is 66.4% after adding FS.
