摘　　要：通过实验研究了沙质滩涂对可溶性油吸附的基本规律以及吸附等温线关系,分析了沙质滩涂粒径、温度、pH和盐度与吸附量的关系。研究结果表明,各沙质滩涂体的吸附动力学曲线和吸附等温线分别符合对数型和直线型理想吸附,沙质滩涂对可溶性油的吸附平衡时间约为10 h;沙质滩涂对海水中可溶性油的吸附量随盐度增加和滩涂体粒度变细其吸附量越大,随温度和pH值的增大而减小。The absorption behavior and isotherms of oil in water by the sands were studied in the experiment. The relations of the absorption capacity with sands under the different size of sands, temperature, pH and salt content were analyzed. The research results show that the dynamic adsorption curves of the oil in water for the sands are logarithmic and all of the adsorption isotherms are straight, the equilibrium period of the adsorption is about 10 hours, adsorption of aqueous oil on the sands are increased with the increase of salinity and the more fine the sands, while is decreased with the increase of temperatures and pH value.
