| 摘 要： | 为了研究海洋沉积物对0#柴油配制的石油溶液的吸附解吸规律,采集了厦门湾15个站点的沉积物作为研究对象,分析了沉积物的主要理化特征之后,在实验室条件下,以SS5号站点沉积物为代表,模拟沉积物对石油的吸附-解吸过程,测定了沉积物对石油吸附、解吸的动力学曲线和吸附等温线.研究结果表明：沉积物对石油的吸附的平衡时间为0.76 h,解吸的平衡时间为7.8 h,沉积物对石油的吸附速率高于解吸速率,并且石油被沉积物吸附以后不会完全解吸出来.沉积物对石油的吸附等温线具有线性规律,接近理想吸附.研究还表明：沉积物对石油的吸附量与石油的浓度,沉积物粒径等因素有关.

| Abstract: | In order to study the adsorption-desorption ability of different sediments to oil,sediments from 15 sites in Xiamen Bay were collected as samples. After analyzed the physicochemical properties, the kinetic curve and isothermal curve of oil-adsorption/desorption process were determined by simulating their adsorption-desorption process to oil. It shows that the speed of adsorption exceeds that of desorption, and the oil had not completely desorption after being adsorbed. The isothermal curve of sediment＇ s adsorption to oil obeys the linear principle and belongs to ideal adsorption. Moreover,the amount of oil adsorbed by sediments is related to the concentration, the particle size of sediments, and some other factors. |
