摘　　要：采用平衡吸附法研究莠去津在2种土壤中的吸附行为,探讨有机质和pH值等因素对莠去津吸附的影响.结果表明,有机质含量与莠去津的吸附量呈正相关,是有机污染物吸附的主要影响因素;pH值与莠去津的吸附量呈负相关,随pH的升高莠去津的吸附量减少.Adsorption behaviors of atrazine in soil studied by oscillation balance method, meanwhile, influencing factor of atrazine adsorption in soil（OM and pH） were also studied. The results showed that organic content of the soil sample was the most important factor affecting the atrazine capacity, the highest capacity was found in soil with the highest or- ganic content. The capacity of atrazine was higher at a lower pH of the soil.
