2015-08-12 · The combination of surfactant enhanced soil washing and degradation of nitrobenzene (NB) in effluent with persulfate was investigated to remediate NB contaminated soil. Aqueous solution of sodium dodecylbenzenesulfonate (SDBS, 24.0 mmol L-1) was used at a given mass ratio of solution to soil (20:1) to extract NB contaminated soil (47.3 mg kg-1), resulting in NB desorption removal .

The soil washing process achieved contaminant removal below targeted levels in 95% of the soil. A traditional remediation strategy would have involved airlifting contaminated soil to the mainland and trucking it to a landfill, whereas the innovative approach allowed for 95% of the soil to be remediated and left on site, with only a small volume of material to be disposed of or recycled.
