Biosurfactant produced by Nocardia amarae grown on hexadecane as a carbon source is being investigated for use in a surfactant/non-ionic organic chemical (NOC) sorption process. Recent experiments at the Illinois Institute of Technology give favorable results using the synthetic surfactant sodium dodecylsulfate (SDS) adsorbed onto ferrihydrite as a removal mechanism for NOC's. Biosurfactant is isolated, characterized, and tested for its adsorbability onto ferrihydrite as well as its potential for NOC removal. Results are being compared to work completed on synthetic surfactant/NOC removal.
