摘要
试样经盐酸—硝酸分解,以王水为介质,采用火焰原子吸收分光光度法测定锡精矿中的银。加标回收率在96%~108.6%之间,相对标准偏差为0.77%~4.0%。
the sample was decomposed by hydrochloric acid and nitric acid, and the silver in tin con- centrate was determined by Flame Atomic Absorption Spectrophotometry in aqua regia. The recovery of the standard was between 96% and 108.6%, the relative standard deviation was 0. 77% to 4. 0%.
