Abstract

Iron-based amorphous crystalline powder Fe78Si9B13AP is used as a permeability reaction barrier (PRB) combined with an electrokinetic method (EK-PRB) to study the removal rate of Cu in contaminated soil. After treating Cucontaminated soil for 5 days under different voltage gradients and soil water content, the soil pH is between 3.1 and 7.2. The increase of voltage gradient and soil water content can effectively promote the movement of Cu2+ to the cathode. The voltage gradient is 3 V/cm, and the water content of 40% is considered to be an optional experimental condition. Therefore, under this condition, the effects of Fe78Si9B13AP 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 studied. Compared with ZVI, Fe78Si9B13AP as PRB has a better remediation effect. EK-Fe78Si9B13AP 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.
