Simultaneous determination of carbaryl and atrazine in water by SPE-HPLC

An Yongsheng;Zhao Linlin;Jiyuan City Key Laboratory of Heavy-Mental Monitoring and Pollution Control;  
The correlation coefficients R~2 were0.9993,for carbaryl and atrazine in the range of 0.5-20ug/L.When the injection volume was 2.500 ml,the carbaryl detection limit was 0.004μg/L,its relative error was from-5.1% to-1.5%,the relative standard deviation was 0.29%-0.97%,the atrazine detection limit was 0.008μg/L,its relative error was-3.5%-5%,and the relative standard deviation was1.5%~2.8%.The standard addition recoveries were 91.8%-104%,91.6%-101%for carbaryl and atrazine respectively.This method is rapid and accurate for the simultaneous determination of carbaryl and atrazine in water.
