摘要: 本文研究了"堿土(Ⅱ)-稀土(Ⅲ)-茜紫-氯化+四烷基吡啶"共顯色體系,確定了最佳顯色條件。此共顯色是形成雜多核配合物所引起。實驗結果得出:參與共顯色的金屬離子半徑比在此共顯色效應中起著重要作用,其大小在一定范圍內時,共顯色強度基本相同,否則共顯色強度就會減弱,甚至不發生;在固定顯色劑的情況下,根據半徑與半徑比相近尋找新的共顯色體系是有一定可能的,但不同的體系有不同的最佳半徑比范圍;金屬離子水解能力的差別對此共顯色體系影響不大。Abstract: The optimum conditions for the co-coloration effect of theco-colored heteropolynuclear coordination compounds in the system of "Alkaline earths(Ⅱ)-Rare earths(Ⅲ).Alizarin violet-Tetradecylpy ridinium chloride" are reported. By analysis of the experimental results, it comes to the following conclusions; the radius of ion or ratios of radii, but not the hyclrolytic properties of the metal ions, play an important role in the co-coloralion of the heteropolynuclear coordination compounds. There is a possibility to search for a new co-coloration system, though different system has different optimum ratio of the radii.
