| Abstract: | A chemical vapor generation(CVG) and inductively coupled plasma mass spectrometric(ICP MS) method was proposed for the simultaneous determination of ultra-trace level of As,Sb,Bi,Ge,Sn,and Hg in coastal and estuarine seawater.Effects of operating parameters,including concentrations of KBH4,HCl and thiourea,pump flow rate and carrier gas flow rate on analytical performance were studied.The results showed that good signal to noise(S/N) ratios for all the analysed elements were obtained when 0.70% HCl,0.10 g/L... |
