%X Representative sands were sampled on the basis of the investigation into the oil contamination of soil-water systems in the Jiaozhou-Bay. Kinetic curves and isotherms of aqueous oil adsorption on sands were measured and the influence of sand contents, sands under different size, temperature, pH and salt contents on the adsorption were studied. The research results show that dynamic curves of aqueous oil adsorption for sands are logarithmic and all the adsorption isotherms are straight, the equilibrium period of the adsorption is 6-10 hours, adsorption of aqueous oil on sands decreases with the increase of the sand contents,temperatures and pH, while increases with the increase of salinity and the more fine of the sands sizes. In addition, it was found that the sands release some oil when the aqueous oil concentrations are lower than certain values.
