| Abstract: | A MD-Fl-HG-AAS methodof Selenium in milk is studied in this paper. The sample is digested by HON 3 and HCIO4 (4:1) in MDS.The digested sample solution,HC1 and NaBH4 and injected voluntarily into AAS through 3 difrent plastics capillary.The detection limit ot the method is 0.41ng.L -1 .The RSD of the method is 3.54%. |
