摘　　要：研究了模拟太阳光作用下2-氯萘在土壤中的光降解动力学及影响因素。结果表明:2-氯萘的光降解符合一级动力学方程;其光降解率随土壤粒径的增加而增大,随土壤厚度和腐殖酸添加量的增加而减少,酸性条件对其光降解具有促进作用。The photodegradation of 2-chloronaphthalene （2-CN） in soil was studied under the simulated solar light, including the kinetics and influence factors. The results showed that the photodegradation of 2-CN fitted the first order kinetics equation ; the photodegradation ratio of 2-CN increased with the increasing of soil particle size, and decreased with the increasing of soil depth and humic acid content; acidic conditions played an promoting role.
