| Abstract: | An analytical method for the simultaneous determination of Na, Cd, Sn, Ba, Pb, Mg, A1, Ca, Cr, Cu, Zn and K in elements dialysis water by high resolution inductively coupled plasma-mass spectrometry（HR- ICP-MS） is studied in this paper. The optimal determination isotopes and appropriate resolutions for the 12 elements are selected to avoid the main spectra interferences from polyatomic ions and double charged i- ons. The results show that the detection limits are 0. 002 to 1.5gg/L , the recoveries of standard addition are 90% to 102%, and the relative standard deviations are in the range of 0.53%-5.83%. |
