Abstract: The adsorption behavior of oleic diethanolamide (ODEA) in water - soil system was studied by oscillating equilibrium method. The adsorption kinetic characteristics and adsorption isotherm curves of ODEA lubricating oil in the system were investigated. The lube oil and the ODEA lube both are absorbed by soil quickly. The adsorption dynamic curve conforms to the Lagergren pseudo-second-order dynamics equation, and the adsorption isothermal curve accords with the Freundlich adsorption isothermal model and the Henry liner adsorption isothermal model. ODEA can inhibit the adsorption capacity and rate of lubricating oil in the soil, while the concentration of ODEA of 4mg/L is the best.

Key words: oleic diethanolamide, adsorption, soil, lubricanting oil
