| Abstract: | By using the method extracted organic phosphorus pesticide used C18 and detected with GC/ FPD, five kinds of organic phosphorus pesticide residues in drinking water are determined. C18 was activated by methanol/water and eluted with chloride / n--hexane, the measured volume was 1.00mL. The extraction time, elution volume and the hydrogen flow rate were discussed as well. This method can be used for the determination of malathion, dimethoate, parathion, phorate and dichlorvos in drinking water. |
