Design of Soil Remediation Techniques from Column Leaching Test Results

The soil remediation at a contaminated site requires knowledge of contaminant transport parameters and processes. This paper presents the determination from column leaching tests in context with two techniques i.e., washing immobilization. To evaluate technique, on polluted were conducted diluted acid solutions hydrochloric acid, ethylene diamine tetraacetic ferric chloride to efficiencies selected solutions. It was observed that efficiency solution higher as it removed percentage metals soil. From these test results, retardation factor dispersion coefficient determined which are useful calculate volume will be required for site. As part immobilization study this soil, mixed amendments (lime, sodium hydroxide cement) increase pH 10 factors estimated through batch results. different obtained lime addition found than other amendments.To analyze long-term stability amended mixtures, samples estimated. also concluded effiencies directly related factors.
