摘要
采用王水分解样品,以10%的王水代替20%HCl浸取样品并作为测定介质,火焰原子吸收法测定岩石样品中的微量银,测定范围为0.3～500g/t。该方法简单、快速,成本低,测定结果准确。
Trace Ag in rock is determined by Flame Atomic Absorption Spectrometry （AAS） with aqua regia dissolving rock sample. 20 % HCl is replaced by 10 % aqua regia as extracting solution and determination media. The determining range of the method is between 0.3 and 500 μg/mL. The method is fast, low cost, easy to operate and the result is accurate.
