Advancement in Research on Application of Steel Slag in Treatment of Mild to Moderate Heavy Metal Contaminated Acidic Soil

Amendment in situ treatment Technology was the most important method for remediation of acid heavy metal contaminated soil, and the selection of cost-effective amendments was the key of this measure. This study describes the major domestic and foreign fixed-stabilizing amendments used, and systematic analyse the role of the composition of the slag on soil PH value, heavy activity and soil nutrients based on the physicochemical properties of slag,we pointed out the potential of steel slag applied in remediation on heavy metal contaminated soil to provide theory reference for remediation of heavy metal contaminated soil.
