Advances in Cd Remediation Techniques for Contaminated Soils

Abstract For heavy metal Cd pollution, here are two general ideas for solving Cd pollution. Firstly, Cd separated or extracted from the soil and decreased in soil Cd content. Secondly, the existence of Cd were changed in soil, reduced its mobility and bioavailability. At present Cd contaminated soil remediation technology is divided into three main categories: physical remediation technology, chemical remediation technology, bioremediation technology.
