高纯金属铯中光度测定痕量氯的资料未见有发表。痕量氯离子的吸光光度测定方法较多,硝酸汞-二苯卡巴腙(苯萃取)法的原理是汞-二苯卡巴腙的紫色络合物由于加入氯离子而退色,此法能测定0.1~1ppm的氯离子,干扰离子较少,在遮光的分液漏斗中显色液稳定,但遮光萃取操作麻烦。为此对水溶液中显色的方法进行了研究。作者加入掩蔽剂以捎除其它离子干扰,获得重现性良好的结果。水相显色探作简单,不用苯,裣量线在0.1~1ppm范围内符合比尔定律。金属铯是碱金属中最活泼的元素,遇空气或水反应相当激烈,作者设计了金属铯的溶解装置,有效地应用于样品分析中。
High purity metal cesium photometry trace chlorine no information published. Trace chloride ion absorption spectrophotometry, mercury nitrate - diphenylcarbazone (benzene extraction) principle is mercury - diphenylcarbazone purple complex due to the addition of chloride ions and fade, this method can determine the 0.1 ~ 1ppm of chloride ions, less interference ions in the shading of the separatory funnel color liquid stability, but shading extraction operation cumbersome. For this reason, the method of color development in aqueous solution has been studied. The authors add masking agents to get rid of other interferences and get good reproducibility. Water color exploration for simple, without benzene, 裣 line in the range of 0.1 ~ 1ppm Beer’s law. Metal cesium is the most active element of alkali metals, the reaction of air or water is quite intense, the author designed a metal cesium dissolution device, effectively used in sample analysis.
