| Abstract: | Samples were dissolved by digestion with HNO3 and emulsion dodecyl sodium sulfate,and the solutions were diluted to a definite volume and used for determination of 17 trace elements Be,B,Al,Ti,Cr,Zn,As,Se,Ag,Cd,Sn,Sb,I,Nd,Hg,Tl and Pb by ICP-MS with octopole collision/reaction system.Pretreatment method and analytical conditions of ICP-MS were optimized in quantification to afford elimination of mass spectral interferences.Detection limits(3S) of the 17 harmful elements were determined and the values obtain... |
