Chemical-Induced Washing Remediation of Metal-Contaminated Soils

摘要: The immobilization or removal of toxic components using aqueous extractants, with without additives, is one the commonly practiced techniques for treatment metal-contaminated soils. However, rather than use water alone, solution chemical-additives preferred due to less time requirement and better separation effectiveness. There a long-favored list additives that have been used chemical-induced washing remediation soils, which include acids, bases, chelants, surfactants, so forth. objective this chapter provide brief overview chemical-assisted soil approaches.
