Soils polluted by metals and organic compounds are a major challenge in soil remediation and environmental recovery; however, the technology to efficiently decontaminate soils polluted by both metal and organic pollutants does not yet exist. Most of these soils are disposed of in landfills. This study first evaluates chemical reagents (hydrochloric, nitric, sulfuric and lactic acids and ethanol) for leaching metals from soil. Assays were then conducted to evaluate non-ionic, ionic and amphoteric surfactants for pentachlorophenol (PCP) removal by flotation. Finally, a laboratory-scale leaching/flotation process was applied to treat four soil samples polluted with both organic ([PCP]i?=?2.5 30 mg?kg?1) and metals ([As]i?=?50 250 mg?kg?1, [Cr]i?=?35 220 mg?kg?1, [Cu]i?=?80 350 mg?kg?1) compounds. The organic compounds and metals are concentrated in the froth and liquid fractions, respectively. Removal yields of 82 93 %, 30 80 %, 79 90 % and 36 78 % were obtained from As, Cr, Cu and PCP, respectively, under optimized process conditions (H2SO4?=?1 N, [cocamidopropyl betaine]i?=?1 % (w w?1), t?=?60 min, T?=?60 C, PD?=?10 % (w v?1)). The treatment of the produced leachate was also tested by chemical precipitation using different reagents.
