Electrodialytic remediation was applied to a shooting range soil to investigate the influence of electrode placement on the removal and binding of metals during the treatment. The set-up was based on a 2-compartment cell, in which the cathode was separated from the soil by a cation exchange membrane and the anode was placed directly in the soil, thereby introducing protons and oxygen directly in the soil. Mobilisation of metals from less available fractions (oxidisable and residual) in the soil occurred, due to oxidation/dissolution of insoluble/soluble organic matter and possibly metal oxides in the residual fraction.

The transport via electromigration out of the soil and/or re-precipitation in other fractions of the soil (oxidisable, reducible, exchangeable) depended on the metal. More than 30% of the initial content of Mn, Cd, Cu, Pb and Zn and less than 20% of the initial content of Al, Fe, K, Mg, As, Cr and Ni was transported out of the soil. By decreasing the distance between the electrodes from 3.0 to 1.5 cm, the removal of the targeted metal for remediation, Pb, was improved by more than 200%, from 14 to 31%. A similar removal could be achieved in experiments with long distance between electrodes (3.0 cm) by increasing the current intensity from 4 to 10 mA and/or the remediation time from 7 to 35 d. The experiments showed that the design and optimisation of electrodialytic remediation depends on the targeted metal and metal partitioning.

将电渗析修复应用于靶场土壤，以研究电极放置对处理过程中金属的去除和结合的影响。该装置基于2隔室，其中阴极通过阳离子交换膜与土壤分开，阳极直接置于土壤中，从而将质子和氧直接引入土壤中。由于不溶性/可溶性有机物和可能的金属氧化物在残留物中的氧化/溶解，使土壤中的有效成分（可氧化的和残留的）中的金属动员。

通过电迁移从土壤中迁移出来和/或在土壤的其他部分（可氧化，可还原，可交换）中再沉淀取决于金属。Mn，Cd，Cu，Pb和Zn初始含量的30％以上，以及Al，Fe，K，Mg，As，Cr和Ni初始含量的20％以下从土壤中运出。通过将电极之间的距离从3.0厘米缩短到1.5厘米，可以将要修复的目标金属Pb的去除率提高了200％以上，从14％提高到31％。在电极之间长距离（3.0 cm）的实验中，可以通过将电流强度从4 mA增加到10 mA和/或将补救时间从7 d增加到35 d来实现类似的去除效果。实验表明，电渗析修复的设计和优化取决于目标金属和金属分配。
