摘要
应用植物酶抑制技术检测蔬菜中的有机磷及氨基甲酸酯类农药 .用小柱对样品进行预处理 ,可去除叶绿素的干扰、提高检测灵敏度 .提出了抑制率阈值 ( 1 5 % ) .应用本方法对市售蔬菜的农药残留进行了调查 ,检出率约为 1 0 % .
A detection method for pesticide residues in vegetables has been developed using a plant- hydrolyses inhibition technique.The chlorophyll exiting in vegetables has been removed using a minicolumn filled with Celite 545.Thus the method sensitivity has been improved.The threshold of percent inhibition is suggested(15%).The developed method has been applied to a vegetable survey in market.
