In this paper, the Batch experiments methods were used to acquire the sorption isotherm, which were were conducted to quantify the contributions to adsorption and compare adsorption characteristics of butachlor with three kinds of soils. Through the experiments, the adsorption characteristic of butachlor in three types of soil contain different organic matter and the factors influencing butachlor adsorption by changing the factors such as quantity of soil ,temperature and pH value of butachlor were studied. The result of the experiment indicates that the balance time of the adsorption of butachlor on three soils is about 12h. And the main one is celerity adsorption. The quantity of organic matter in soil is the most important factor influence the adsorption of butachlor, the quantity of organic matter in soil is positive correlation with the adsorption of pesticide on soil .The more soil it put the more quantity it adsorbed, the quantity of adsorption of pesticide on soil is decreased along with the temperature increased,but the infection is not evidence; Alkalescency is not good for adsorption.
