ABSTRACT = {Iron-based amorphous crystalline powder Fe<sub>78</sub>Si<sub>9</sub>B<sub>13</sub><sup>AP</sup> 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
Cu<sup>2+</sup> 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 Fe<sub>78</sub>Si<sub>9</sub>B<sub>13</sub><sup>AP</sup> 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, Fe<sub>78</sub>Si<sub>9</sub>B<sub>13</sub><sup>AP</sup> as PRB has a better remediation effect. EK-Fe<sub>78</sub>Si<sub>9</sub>B<sub>13</sub><sup>AP</sup> 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.},
