Investigation of Electrokinetic Remediation of Arsenic-Contaminated Two Different Soils (Alluvial And Red Clay Soil) from Tamilnadu

Abstract

The capability of electrokinetic (EK) remediation innovation has been effectively exhibited for the remediation of heavy metal-contaminated fine-grained soils through lab scale and field application contemplates. Arsenic contamination in soil is a difficult issue influencing both site use and groundwater quality. The EK innovation was assessed for the expulsion of arsenic from two soil tests; alluvial mud soil and red mud soil taken from the Tamilnadu zone. The viability of upgrading specialists was examined utilizing three unique kinds of cathodic electrolytes; deionized water (DIW), potassium phosphate (KH2PO4) and sodium hydroxide (NaOH). The consequences of the examinations on the alluvial mud soil show that the potassium phosphate was the best in extricating arsenic, likely because of anion trade of arsenic species by phosphate.Then again, the sodium hydroxide appeared to be the most proficient in eliminating arsenic from the red soil. This outcome might be clarified by the way that the sodium hydroxide expanded the soil pH and quickened ionic relocation of arsenic species through the desorption of arsenic species just as the disintegration of arsenic-bearing minerals.
