摘　　要：以0#柴油为研究对象,探讨了石油污染物在海滩颗粒体系中的吸附规律,考察了吸附剂(沙粒)的粒径、海水盐度和温度三因素对吸附作用的影响,并对吸附机理进行了分析。结果表明,颗粒物对溶解油的吸附速率较快,其吸附量与沙粒粒径成反比,与盐度成正比,而温度的升高不利于吸附过程的进行。溶解油在颗粒物上的吸附为物理吸附,其吸附模式符合Henery等温吸附式。Taking the 0 # diesel oil as the research object, this article discussed the role of the oil pollutants adsorption in the system of foreshore, the influnce of the sorbents diameter ,temperature and salinity on the adsorption was studied , and the adsorption mechanism was also analysed . Results show that the dissolved oil was adsorped by the sorbent rapidly , the adsorption amount was inversely proportional to the diameter of sorbent and directly proportional to the salinity, while the temperature increment was adverse to the adsorption. The course of dissolved oils adsorption by the adsorbent is physical adsorption, and its adsorption mode is the Henery adsorption isotherm.
