摘　　要：随着高新技术领域的快速发展,对高纯无机盐的需求日益增加。高纯无机盐中杂质元素的存在,会不同程度地影响其应用性能,因此需对杂质离子含量进行严格限制并准确检测。仪器分析在产品纯度测定、所含杂质物质的种类和含量测定等方面具有不可替代的作用。以高纯硝酸银为例,对比了国内外无机盐产品的技术指标和分析检测方法,进一步对高纯无机盐中痕量杂质的检测方法,主要包括原子吸收光谱法和电感耦合等离子体光谱法进行了综述。In recent years,the demand for high purity inorganic salts by various high-technology industries has increased.Because impurities in inorganic salts could effects the properties,it is significant to control strictly impurities and to develop determination methods.In this work,the technique index for high purity inorganic salts at home and abroad was compared firstly. And then,the determination methods were reviewed,mainly including atomic absorption spectroscopy and inductively coupled plasma atomic emission spectrometry,for high purity inorganic salts.
