摘要
用硝酸与硫酸消解处理废定影液样品，能将样品中硫代硫酸络合物与离子完全破坏形成硫黢基体的可待测溶液，用ICP—AES电感藕合等离子原子发射光谱仪对样品进行银含量测试。方法的精密度小于2．4％，加标回收率在99．1％～101．1％之间，与其余三种银含量分析方法对照结果基本一致。
Argentine determinaton in the waste fixative liquid by Indutively Coupled Plasma-Automic Emission Spectum and decompose thiosulfonic ion completely into liquid after clear up the it by nitric acid and vitriol.The extraction ratio of the standard substance added is between 99.1%-101.1%,R.S.D〈2.4%.The results is accord etcerera three Argentine determination methods.
