| Abstract: | Soil cadmium pollution has become a serious environmental and public health problem, which has gained increasingly close attention from people, using clay minerals remediation Cd contaminated soil was an effective technique. In order to promote the rapid development of remediation in heavy metal contaminated soil effectively, the paper summarized the influence factors of clay minerals in remediation of soil Cd, including the type, dosage and modification of clay minerals, and soil pH, degree of soil pollution et al, analyzed its remediation mechanism of adsorption and precipitation on basis of the study properties of clay minerals, results showed that remediation effect was good. Finally, the paper put forward the future direction of research in this field |
