【摘要】 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。更多还原

【Abstract】 Through static (agitating)experiment,the absorption and desorption behaviour of oil by sediment is Studied.The absorption of oil by sediment in river is physical absorption and subordinated to Langmuir Freundlich absorption isotherm equation.The process between absorption and desorption is not reversible.The oil absorbed to sediment can not be desorbed completely in water.Sediment grain size and concentration,electrolyte(salt)concentration,and oil concentration are the main factors effecting on the alsorption capacity.In this paper the absoption isotherm equation,desorption equation,minimum remains equation and the relational formula of absorption capacity and minimum remains with grain size are established with experimental data.更多还原
