Abstract

The opportunity to use deoxycholic acid (DA), bovine bile (BB), and the residue resulting from DA extraction from BB (BBR) as nontoxic and biodegradable pollutant-mobilizing agents in the washing of (chloro)aromatic-contaminated soils was studied. They were applied in parallel to Triton X 100 and evaluated for their ability to mobilize pollutants from a contminated soil and to influence the aerobic treatment of the resulting effluents. The soil was suspended at 15% (w/v) in water or in water with 1.0% (w/v) DA, BB, BBR or TX in batch reactors shaken at 120 rpm for 24 h. The resulting effluents were treated in shaken batch reactors at 20°C for 56 days. The biogenic agents enhanced by 227÷441% the pollutant mobilizing capability of water by also sustaining the effluent aerobic bioremediation. TX enhanced the same process by about 536% but increased the soil toxicity and adversely affected the biotreatability of the resulting effluent.
