Abstract

The study was conducted to understand the feasibility of remediation of heavy metals (HM) from contaminated soil using tartaric acid, citric acid and Ethylene Diamine Tetra Acetic acid (EDTA) solution. The chemical reagents used for the study are environment-friendly extractants, which are less expensive. The soil samples are collected from three different stations surrounding Titanium Travancore Pvt. Ltd (TTPL) industry during the months of August and September of the year 2016. As an initial study the collected soil samples are taken for physical and chemical analysis. It was noted that the sample was acidic in nature. It was noted that the collected soil sample has very low organic and nutrient contents. The sample was then mixed with tartaric acid, citric acid and EDTA solutions in separate open beakers and kept for three months. At the end of the study, it was recorded that the concentrations of HMs in the soil samples mixed with tartaric acid has reduced drastically compared with other two mixes. Also the soil heavy metal concentration was high in the station near the waste and effluent discharging points compared to that in the other two stations of the study area.
