In-Situ immobilization of heavy-metal contaminated soil by electrokinetic phosphoric acid injection

摘要

The subject innovation is the electrokinetic remediation of lead-contaminated soil to purify the contaminated soil processing apparatus with a mixed solution containing the injection in the soil contaminated with lead to immobilization of lead in situ effectively by making the water-insoluble using the electrokinetic It relates.; The subject innovation is an acid that contains a chlorine (Cl) component solution containing a (P) (HCl) and mixed with the soil contaminants by moving the contaminated area in the soil by electrical ion migration phenomenon of electrokinetic techniques lead the Sikkim significantly reduced the amount of elution by excellent in fixing efficiency of lead soil by immobilized in the soil, as well as drilling, transport of the contaminated soil, no treatment needs to heavy metals, or the structure on the top it is possible to purify the soil where drilling is difficult in contaminated soil remediation as effective.
