摘要
报道了用液相色谱法测定微量氨基甲酸酯农药的方法，氨基甲酸酯先在碱性条件水解，生成的酚用液相色谱安培法测定。研究了最优色谱条件。该法简单、快速、灵敏，已应用于测定大米中克百威、西维因、异丙威和甲硫威４种氨基甲酸酯农药残留量。
A high performance liquid chromatographic method for the determination of phenolic moieties in N_methylcarbamates at a level of tens of a picogram is described.Carbamates were hydrolyzed under alkaline conditions,and the resulting phenols were then determined by HPLC with an amperometric detector.Optimum analytical conditions have been studied.The method has been tested with four carbamates (carbofuran,carbaryl,isoprocarb and methiocarb)in rice samples.The method is simple,rapid,and sensitive.It can be applied for routine analyses of carbamate residues.
