Removal of Lead from Wastewater Using a Biosurfactant

Lead removal form wastewater was studied using the UH-biosurfactant. Lead concentration varied from 10 to 100 mg/L and pH varied from 2.5 to 12. Commercially available surfactants such as SDS and Triton X-100 were also used for comparison. Results have shown that biosurfactant removed over 75% of lead from water and the optimum lead-biosurfactant ratio was 0.01.
