ABSTRACT
Objective To establish a method for simultaneous determination of 6 kinds of organophosphorus pesticides in water.Methods The liquid-liquid extraction,gas chromatography with RTX-50 capillary column and flame photometric detector were used to determine 6 kinds of organophosphorus pesticides(DDVP,dimethoate,malathion,methyl parathion,parathion,chlorpyrifos)in water.Results Chromatographic resolutions for the above 6 kinds of organophosphorus pesticides were both over 1.5.The linear range was 2.0-16.0 ?g/ml(r=0.999 2~0.999 8),the detection limits were 0.009 2~0.076 ng,RSDs were 1.5%-7.1%,the average recovery rates were 93.0%-98.7%.6 kinds of organophosphorus pesticides could be absolutely separated on RTX-50 capillary column.Conclusion This method presents an advantage in detection limit,precision and accuracy compared with that in GB13192-1991,it will meet the requirement of Sanitary Standard for Drinking Water and routine water quality analysis.
