摘要
综述了近十年来国内外对不同含量铟的分析方法的研究进展情况。内容包括常量铟、微量铟以及痕量铟的分析方法。在常量铟的分析方法中,络合滴定法是目前应用最广泛的一种方法,其次是原子吸收光谱法和极谱法。在微量铟的分析方法中,分光光度法属于研究的最多且最活跃的领域,该方法一般采用荧光酮类、偶氮类以及各种染料类试剂作为显色剂,与铟呈灵敏的显色反应;另外,原子吸收光谱法、电化学分析方法也是微量铟分析的重要方法。对于痕量铟的分析,目前主要采用石墨炉原子吸收光谱法和电热原子吸收光谱法,由于铟含量非常少,在测定前,大多需要对铟进行分离富集;另外,文中也报道了直接测定痕量铟的方法,但是关于这方面的报道比较少。在不同含量的每一种铟分析方法中,主要从测定方法、测定条件、测定结果等方面进行了归纳和概述。
This review has summarized the advance of analytical methods for indium in different content level over the last decade,including macro indium,micro indium and trace indium.Among the analytical methods for macro indium,complexometry is the most widely applied technique at present,followed by atomic absorption spectroscopy and polarography.Among the analytical methods for micro indium,spectrophotometry is the most popular.In spectrophotometry,fluorone reagents,azo compounds and dyestuff series are used as chromogenic reagents,which occurs a sensitive color reaction with indium.In addition,atomic absorption spectroscopy and electrochemical method are also very important analytical methods for micro indium.Among the analytical methods for trace indium,graphite furnace atomic absorption spectrometry and electrothermal atomic absorption spectrometry have been widely used.Because the content of indium is very low,separation and enrichment of indium become great important before determination of indium.In addition,the methods for direct determination of trace indium have also been reported,but there are only a few reports.The references of every method for indium in different content level were summarized from the aspects of determination methods,conditions,results,etc.
