| 摘 要： | 硝酸溶解—火试金法测定银阳极板中金含量的方法是基于银易溶于硝酸而金不溶于硝酸的性质,采用硝酸溶解银阳极板,经过沉淀、过滤、灼烧后,再用火试金法进行金含量的测定。该法干扰少、准确度高、精密度好,RSD为0.2%。

| Abstract: | The determination of the gold content in silver anode plate by using nitric acid dissolution-fire assay procedure is based on that the silver can be dissolved easily and the gold can＇t be dissolved in nitric acid,and the gold content can be determined through dissolving silver anode plate in nitric acid and after precipatating,filtrating and igniting. The metnod has less interference,high accuracy and good precision with RSD （relative standard deviation） of 0.2%. |
