高纯碱金属盐中杂质测定方法的研究进展

摘要

高纯碱金属盐的纯度对其应用有很大影响,痕量杂质元素含量的严格控制和准确测定非常重要.本文对高纯碱金属盐中的杂质分析方法(原子吸收光谱法、分光光度法、电感耦合等离子体光谱法、电感耦合等离子体质谱法、离子色谱法等)进行了综述.%The purity of high purity alkali metal salt effects the application a lot. The strictly control and accurate determination of trace impurity is very important. The analysis methods (atomic absorption spectrometry, spectrophotometry, ICP-AES, ICP-MS, ion chromatography) for impurities in high purity alkali metal salt are summarized in this paper.
