开发了一种离子相互作用 HPLC 方法，用于分离苯脲类除草剂 asulam、敌草隆、异丙隆、利谷隆和莫谷隆。以C18为固定相，磷酸辛铵为离子相互作用试剂，甲醇或乙腈为有机改性剂。无需预浓缩步骤即可获得低于 9 μg/l 的检测限。该方法适用于泻湖水样中敌草隆的分析。使用液-液萃取，发现敌草隆浓度为 42 μg/l。
An ion-interaction HPLC method is developed for the separation of the phenylurea herbicides asulam, diuron, isoproturon, linuron and monuron. C18was used as stationary phase and octylammonium phosphate as ion-interaction reagent, in the presence of methanol or acetonitrile as organic modifier. Detection limits lower than 9 μg/l can be obtained without preconcentration steps. The method was applied to the analysis of diuron in a sample of lagoon water. Using liquid-liquid extraction, a diuron concentration of 42 μg/l was found.
