Soil remediation for contaminated soil from heavy metals by electrokinetic process / Sabariah Arbai ... [et al.]

Contaminated sites with heavy metals, organic compounds and hazardous materials added with inefficient waste handling techniques, leakages and untreated abandoned mines made enormous impact to groundwater quality, soils and ecosystems. Electro-chemical principle, known as electrokinetic method is a...
