摘　　要：建立了直接测定水中10种氨基甲酸酯类农药及其代谢物的超高效液相色谱-质谱分析方法。该方法对水样无需进行富集处理,水样过滤后就可以直接测定。实验结果表明:测定液中各氨基甲酸酯类农药及其代谢物的质量浓度与离子对峰面积在质量浓度0.5～1 000.0μg/L内具有良好的线性关系;方法检出限为0.1～5.0μg/L;加标回收率91%～103%;相对标准偏差为2%～5%。该方法具有简便快捷、灵敏度高的特点。The superefficient liquid chromatography-mass spectrometry method for direct determination of 10 carbamates and their metobolits in water was developed.By this method,water samples can be determined directly after filtration without enrichment.The experimental results show that: There is a good linear relation between the mass concentrations of carbamates and their metobolits and the peak areas of the ion pairs in the range of 0.5-1 000.0 μg/L;The detection limits are 0.1-5.0 μg/L;The recoveries of standard addition are 91%-103%;The relative standard deviations are 2%-5%.This method is simple,rapid and sensitive.
