Characteristics and Interaction of Cu~(2+)-Phenanthrene Stripping by Humic Acid in Compound Contaminated Soil

Humic acid was used to remove the copper ion and phenanthrene from contaminated soil as surfactant.Cu2+ and phenanthrene were selected as objects to study characteristics stripping by humic acid.The interaction of Cu2+-phenanthrene was discussed in contaminated soil.The results showed that humic acid had good stripping properties for Cu2+ and phenanthrene.The stripping quantities of Cu2+ and phenanthrene in compound contaminated soil were respectively 516.6 mg/kg and 569.1 mg/kg when the humic acid addition was 5 mg/g soil.Humic acid had good stripping properties for phenanthrene,the change of stripping rate of humic acid on phenanthrene was not obvious with or without the presence of Cu2+.While the stripping of Cu2+ had some antagonistic action under the influence of phenanthrene.
