Surfactant-enhanced extraction of hazardous wastes from soils. First report
Through combined efforts, researchers at Clark Atlanta University and Savannah River Site propose to develop improved soil washing techniques for decontaminating soils containing organic, inorganic and radioactive wastes. This project encompasses several tasks including (1) identification of organic, inorganic and radioactive pollutants in selected soils, (2) separation of soils into various fractions and the determination of wastes in each fraction, (3) soil decontamination by washing with surfactants and evaluation of the effectiveness of various types of surfactants in removing contaminants from soils, (4) determination of soil remediation and the effects of the surfactant concentration and wash solution-to-soil ratio on the desorption and removal of organic wastes from soils, (5) assessment of soil particle size distribution on waste efficiency, (6) evaluating the effects of temperature, mixing rates, and extraction times on waste solubilization and extraction, and (7) determination of the influence of surface charge properties and the pHs of the souls slurries on the decontamination efficiency.
