摘要
在研究乙基罗丹明Ｂ－硅钼杂多酸（ＥＲＢ－ＳｉＭｏ）、乙基罗丹明Ｂ－磷钼杂多酸（ＥＲＢ－ＰＭｏ）、乙基罗丹明Ｂ－锗钼杂多酸（ＥＲＢ－ＧｅＭｏ）缔合物水相光度法测定硅、磷、锗的基础上．应用吸收光谱、红外光谱、摩尔吸光系数对比等方法，对本类缔合物的光度特性及其形成机理进行了探讨．
Based on the determination of sillcon,phosphorus and germanium in the system of ethyl rhodamine B (ERB)-heteropolyacid-PVA by spectrophotometry in aqueous phase,the formation mechanism and the spectral characteristic of the multicomponent complexes of heteropolyacid with basic dyes have been discussed.The complexes are supposed to be ion-associated complexes with the possible formulas of ERB_4[Si(Mo_3O_(10))_4],ERB_4H_3[P(Mo_2O_7)_6]and ERB_4[Ge(Mo_3O_(10))_4].
