| Abstract: | In this paper a continuous flow vapour system hydride generation-atomic absorption spectrophotometry was applied. Samples were dissoluved in aqua regta,exeess HNO3 was completely evaporated by adding H2SO4,and interference elements were affectively covered by O-phenanthroline,then arsenic in steel products was determinated on condition that HCl acidity and KBH4concentration were proper.Satisfactory accuracy and precision were obtained by this method.It is simple and fast. |
