对土壤中原油的解吸动力学及土壤粒径、pH值和温度3个影响因素进行了研究．研究结果表明：土壤中原油的解吸动力学符合Lagergren准二级动力学方程；原油污染土壤粒径越小，解吸的原油量越多；在pH值2～12范围内土壤中原油的解吸量随pH值的增大而增大；随着温度的升高，原油的解吸量逐渐增大．

This paper studies the experimental mvesuganon related oil in soil,such as the desorption kinetics and the three factors of soil particle size, pH and temperature. The results of the research show that the desorption kinetics of crude oil in soil conforms to the available pseudo second order Lagergren adsorption kinetic equation. The smaller the particle size of crude oil contaminated soil, the more volume of crude oil desorption. The Desorption amount of crude oil in soil increases with the increase of the pH value in the range 2～12. With the temperature increasing,the desorption amount of crude oil in soil gradually increases.
