| Abstract: | Objective] Based on GB/T5750.8.17 -2006,detection method for epichlorohydrin in drinking water was further optimized. Method] The epichlorohydrin in drinking water was extracted by organic solvent and then concentrated.Concentrated solution was detected by gas chromatograph with hydrogen flame ion detector ( FID) .Drawing standard curve after test conditions were determined, the linear equa-tion of epichlorohydrin was established.Result] The results showed that the sensitivity, accuracy and linearity of test method is superior to the national standard method.The method can satisfy the basic laboratory requirements for the determination of epoxy epichlorohydrin.Con-clusion] The method for determination of epichlorohydrin in drinking water by liquid liquid extraction capillary gas chromatography was estab-lished. |
