Electrokinetic remediation is a process in which a direct electric current is applied across a section of contaminated soil to remove metals. To improve the electrokinetic remediation in this study, a conductive membrane was fabricated via in situ chemical polymerization employing pyrrole and copper oxide nanoparticles. The fabricated membrane was placed in an electric field as part of the electrode structure. A physical model was constructed and filled with copper-contaminated kaolinite in the concentration of 200 mg/kg. To control the pH, 0.1 M citric acid and 0.01 M potassium chloride were used as the electrolyte solutions. Experimental parameters such as voltage, current, pH, EC, drained flow, and copper concentration were measured. The results showed that the minimum surface resistivity of the fabricated membrane under a maximum pressure of 8.2 kPa was 2.55 kΩ/m². The experimental results demonstrated that the use of citric acid as an electrolyte was more useful to desorb the copper due to the formation of the copper-citrate complex. When employing the fabricated membrane, the copper removal increased from 13% (in CT-2) to 63% (in GM-2), while the removal of copper using potassium chloride electrolyte increased from 42% (in CT-1) to 52% (in GM-1). The highest power consumption was obtained in experiments using citric acid. Due to the higher removal efficiency of copper in GM-2, the energy utilization efficiency (β) increased and reached 29.9 near β value of GM-1 with the lowest power consumption.

电动修复是一个过程，在该过程中，在受污染的土壤部分施加直流电以去除金属。为了改进本研究中的电动修复，使用吡咯和氧化铜纳米粒子通过原位化学聚合制备导电膜。将制造的膜作为电极结构的一部分放置在电场中。构建物理模型并填充浓度为 200 mg/kg 的铜污染高岭石。为了控制 pH 值，使用 0.1 M 柠檬酸和 0.01 M 氯化钾作为电解质溶液。测量了电压、电流、pH、EC、排水流量和铜浓度等实验参数。结果表明，在最大压力为 8 的情况下，制备的膜的最小表面电阻率。² . 实验结果表明，由于形成了柠檬酸铜络合物，使用柠檬酸作为电解质更有助于解吸铜。使用制造的膜时，铜去除率从 13%（CT-2 中）增加到 63%（GM-2 中），而使用氯化钾电解质的铜去除率从 42%（CT-1 中）增加到 52 %（在 GM-1 中）。在使用柠檬酸的实验中获得了最高的功耗。由于GM-2中铜的去除效率较高，能源利用效率（β）增加，达到GM-1的β值附近的29.9，功耗最低。
