| 摘 要： | [目的]为土壤中噻苯隆和敌草隆及其代谢物的残留分析建立一种简捷可行的方法。[方法]利用液相色谱法对供试土样中噻苯隆和敌草隆及其代谢物的残留量进行测定。[结果]噻苯隆及其代谢物的最大吸收波长为290nm左右，敌草隆及其代谢物的最大吸收波长为254nm。噻苯隆及其代谢物thidiazolylurea和敌草隆及其代谢物DCPU、DCPMU的线性回归方程分别为：y=0．5704x＋0．0723、Y=2．3635X＋0．2386、Y=0．5687X＋0．108、Y=0．5504x＋0．1163和Y=0．6107X＋0．3612；其最低检出浓度分别为0．04、0．08、0．05、0．04、0．03mg／kg；当添加浓度为其最低检出浓度时，平均加标回收率及其RSD分别为：86．78％和5．51％、95．13％和8．13％、89．04％和6．60％、84．10％和4．29％、92．05％和5．92％。[结论]该方法在定性和定量分析方面都能够满足土壤中噻苯隆和敌草隆及其代谢物的残留量测定分析要求。
