摘要
A simple and sensitive high performance liquid chromatography (HPLC)-UV method has been developed for the analysis of phenylurea herbicides, namely, monuron, diuron, linuron, metazachlor, and metoxuron, that involves a preconcentration step using solid-phase extraction. The mobile phase used was acetonitrile-water at a flow rate of 1 mL/min with direct UV absorbance detection at 210 nm. Separation of analytes was studied on a C18 column. The method was applied successfully to the analysis of the herbicides in three soft drink brands and tap water. Good linearity and repeatability were observed for all the pesticides studied.
