摘要
The absorption behaviour of emulsified oil by sediment (include loess) is studied by experiment. The absorption equation and the relations of absorption capacity with sediment concentration, grain size, salt concentration and temperature are analyzed. The absorbing reaction kinetics process is also studied. The absorption of emulsified oil by sediment in rivers is agreed with the Langmuir-Freundlich absorption equation. Experimental data shows that the larger the equilibrium oil concentration and the salt concentration , the more the absorption capacity. The absorption capacity increases immensely with grain size and temperature reduction.
