二引言锗的测定多采用原子吸收法和分光光度法。通常后者的灵敏度不高，选择性欠佳，其中较好的方法是用锗钼杂多酸与罗丹明６Ｇ（Ｒ６Ｇ）的缔合物测定锗。我们在此基础上，用０．０１ｍｏｌ／Ｌ的ＮａＯＨ解析（Ｒ６Ｇ）４ＧｅＭｏ１２Ｏ４０使Ｒ６Ｇ＋进入水相与加入的四溴 Two Introduction Determination of germanium and more by atomic absorption spectrophotometry. Usually the latter is less sensitive and less selective, and the preferred method is to determine germanium with an association of germanium molybdate and rhodamine 6G (R6G). On this basis, we use NaOH (0.01G / L) to resolve (R6G) 4GeMo12O40 to make R6G + enter the aqueous phase with the addition of tetrabromobis
