摘　　要：以柴油污染的海水为对象,研究了砂对海水中溶解油的吸附作用及吸附的影响因素。结果表明,砂对溶解油的吸附符合Henry型吸附等温式,其吸附量随着砂粒粒径的减小、温度的降低和盐度的增加而增大。在影响吸附的3种因素中,粒径对吸附的影响最大。通过吸附热力学分析,推断砂对溶解油的吸附属于物理吸附。The adsorption of dissolved petroleum hydrocarbons （DPHs） on sands and the influencing factors were studied using diesel polluted seawater as the object of research. Results show that the adsorption isotherms can be described as Henry＇ s equation, and the adsorption capacity increases with the decrease of particle size and environmental temperature, and with the increment of salinity of seawater. Among all the factors affecting the adsorption capacity, the size of sands is the most notable factor. The adsorption of DPHs on sands belongs to physical adsorption according to the study on adsorption thermodynamics.
