| 摘 要： | 建立了流动注射HG-AFS测定痕量砷和汞的分析方法。把砷和汞放入20%的王水介质中,它们被硫脲-抗坏血酸预还原,待测量溶液澄清之后,将溶液与硼氢化钾一起导入反应器,产生的氢化物载气导入原子化器中测定,测定结果符合国家标准。本法改进了流动注射HG-AFS法测定砷、汞的分析方法。

| Abstract: | In this determination,in 20% aqua regia,As and Hg are prereduced by thiourea-ascorbic acid,after determining solution is settled,conducting solution and sodium borohydride into reactor,the producted hydride conducts into atomizer by carrying gas body to determine As and Hg in geochemical exploration samples by using Hg-AFS flow injection method.The determined result is in correspondence with the standard value.We used liquid filler made by ourselves and constant temperature heating resolution channel made by ourselves,thiourea and ascorbic acid as a reducing agent,to improve HG-AFS flow injection method for determining As and Hg. |

| Keywords: | thiourea and ascorbic acid sodium borohydride determination of As and Hg HG-AFS flow injection method |
