Abstract

Abstract

On the basis of the investigation into the oil contamination of soil-water-plant systems in the Shenyang-Fushun irrigation field, surface soils and bottom soils were sampled along 3 representative profiles and their major physical and chemical properties were analyzed. Kinetic curves and isotherms of aqueous oil adsorption on soils were measured and influence of organic matter, clay particle and salt contents on the adsorption was evaluated. The research results show that the equilibrium period of the adsorption is 20-24 hours, and all the adsorption isotherms are straight. In addition, it was found that the soils release some oil when the aqueous oil concentrations are lower than certain values.
