通过静态（搅拌）实验，研究了河流泥沙对石油乳化油的吸附、解吸和极限残留量变化的基本规律。泥沙对石油乳化油的吸附规律符合Ｌａｎｇｍｕｉｒ－Ｆｒｅｕｎｄｌｉｃｈ等温式，吸附与解吸过程不可逆，在清水中不能完全解吸出来。吸附量与油浓度、沙浓度、沙粒径及溶液中的电解质（盐）浓度等因素有关。根据实验资料建立了吸附等温式、解吸方程、极限残留方程、以及吸附量和极限残留量随泥沙粒径的变化关系式。最后对溶液盐度对吸附的影响作了初步探讨。
By static (agitation) experiments, the basic laws of river sediment on oil emulsion oil adsorption, desorption and the limit residue changes. Sediment oil adsorption law consistent with Langmuir-Freundlich isothermal adsorption and desorption process is irreversible, can not be completely desorbed in water. The amount of adsorption is related to oil concentration, sand concentration, sand particle size and electrolyte (salt) concentration in the solution. Based on the experimental data, the adsorption isotherms, desorption equation, limit residual equation and the relationship between the adsorption capacity and the limit residue with the sediment particle size were established. Finally, the effect of salinity on the adsorption was discussed.
