| Abstract: | According to the heavy metal ion migration transformation rule,the heavy metal pollution in soil can be treated by physical,chemical,biological methods and each repair method has their advantages and disadvantages.Environmental mineralogical method has the advantages of low cost and high efficiency.This paper describes two kinds of representative environmental minerals（silicate and phosphate）from the performance of silicate and phosphate mineral properties,reaction mechanism and effect of heavy metal ions on soil survey of silicates and phosphates research progress in remediation of heavy metal pollution of soil.It also expounded the silicates and phosphates on the different effects of heavy metal ions,as well as the factors affecting its role and proposed current problems and deficiencies. |
| Keywords: | silicate phosphate soil remediation heavy metal pollution |
