摘要
本文应用连续蒸汽产生系统的氢化－原子吸收法，以王水溶解试样，加硫酸驱除过量硝酸。采用邻菲啉有效地掩蔽干扰元素，在适当的盐酸酸度和硼氢化钾浓度下，测定钢铁中砷量。采用本法准确度与精确度均能获满意结果，方法简便、快速。
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.
