摘      要：Iron-based amorphous crystalline powder Fe_(78)Si_(9)B_(13)^(AP)is used as a permeability reaction barrier(PRB)combined with an electrokinetic method(EK-PRB)to study the removal rate of Cu in contaminated *** treating Cucontaminated soil for 5 days under different voltage gradients and soil water content,the soil pH is between 3.1 and *** increase of voltage gradient and soil water content can effectively promote the movement of Cu^(2+) to the *** voltage gradient is 3 V/cm,and the water content of 40%is considered to be an optional experimental ***,under this condition,the effects of Fe_(78)Si_(9)B_(13)^(AP)and zero-valent iron(ZVI)as PRB on the removal rate of total Cu in soil and the transformation of chemical forms of Cu are *** with ZVI,Fe_(78)Si_(9)B_(13)^(AP)as PRB has a better remediation ***-Fe_(78)Si_(9)B_(13)^(AP)can remove 80.3%of total Cu in soil,and the biologically available Cu is reduced to 3.6%,which effectively reduces the environmental risk of contaminated soil.
