| Abstract: | Two methods have been investigated to enhance the chemical vapor generation(CVG) of Au,Pt,Pd,Co,Zn and Mn for inductively coupled plasma atomic emission spectrometry.Sodium tetradecahydroundecaborate(NaB11H14) was used instead of sodium borohydride(NaBH4),which increased the concentration of reductant hydrogen;and the solutions of the metal ions and sodium borohydride were heated to accelerate the reaction.With the first method,the optimal NaB11 H14 concentration was 1.42(m/V),the optimal HNO3 concentration... |
