化学——光谱法测定高纯碱金属化合物中痕量杂质,前人做过大量工作。为了配合本所冶炼研制新产品工艺控制及生产分析,进行了高纯碘化铯中铜、铝、镍、钴、铁、铅、铊及锰八种痕量元索的化学——光谱法试验及控制分析。实践证明,本方法可用于冶炼控制分析。本方法采用吡咯烷二硫代甲酸铵(APDC)、二乙胺硫代甲酸钠(DDTC)、8—羟
Determination of trace amounts of impurities in high purity alkali metal compounds by chemical-optical spectroscopy has done a great deal of work. In order to cope with the process control and production analysis of new products developed by our institute, the chemical-spectral test of eight trace elements of copper, aluminum, nickel, cobalt, iron, lead, thallium and manganese in high purity cesium iodide And control analysis. Practice has proved that this method can be used for smelting control analysis. This method uses ammonium pyrrolidine dithiocarbamate (APDC), sodium diethyldithiocarbamate (DDTC), 8-hydroxy
