| 摘 要： | 室内模拟研究结果表明，电动修复苯胺污染土壤的过程中，添加液的加入对实验结果有较大影响。当腐植酸浓度大于临界胶束浓度时，起表面活性剂的作用，使苯胺在土壤中迁移增强并在距阳极80～90mm富集。土壤中均匀加入Tween80或β-环糊精后，苯胺在3取样点富集，但富集浓度后者是前者的1．28倍，且污染物有向阴极迁移的趋势。

| Abstract: | The results of indoor imitation study showed that adding of additive liquid had bigger impacts on experimental effects in polluted soil restoration with electric power. When concentration of humic acid was bigger than concentration of critical micelle, the role of surface active agent was played, the migration of aminobenzene in soil was increased and enrichment of 80 - 90mm from anode was formed. When Tween80 or β - cyclic dextrin were put in homogeneously, aminobenzene was riched at three sampling sites, and pollutants had trends to migrate toward cathode. |
