Prevention of Groundwater Pollution by Using the Electroosmotic Flushing of Soil Systems

Аннотация

Electrokinetic removal of hydrophobic organic compounds from soil systems of various compositions making it possible to avoid an ingress of toxicants into groundwater has been investigated. Solubilization of impurities was ensured by using aqueous solutions of nonionic surfactants belonging to the group of oxyethylated alkylphenols. The distribution curves of residual impurity content were obtained after the termination of electric treatment of soils following the passage of different volumes of electroosmotic solutions containing surfactants. The specified curves allow us to predict the possibility of achieving the required treatment efficiency.
