摘    要:在水溶液中将脱氧胆酸钠(NaDC)分别与CaCL2、EuCl3及LaCl3反应,改变反应物浓度和配比,合成了系列脱氧胆酸络全物。利用红外光谱(FTIR)、元素分析、ICP分析及X身材线粉末衍射谱,对它们的组成和结构进行了研究。结果表明:水溶液中CaCl2与NaDC的反应不是简单离子间的反应,改变其反应物浓度和配比,生成组成和结构不同的络合物;而LnCl3与NaDC反应时,反应物浓度和配比的改变不影

关 键 词:脱氧胆酸  络合物  胶团  FTIR

Abstract:The interactions of Ca2+ , La3+ and Eu3+ with NaDC were investigated by FTIR spectroscopy, element analysis and ICP analysis separately. The following conclusions have been deduced: (1) The structure and composition of resultants vary with the concentration and initial molar ratio of CaCl2 and NaDC. The resultant can be simple Ca(DC)2 complex with the composition of Ca(DC)2? 3H2O or complicated Ca(DC)2- NaDC complex with gel character and macromolecular network structure.(2) The structure and compositon of resultants obtained by reaction of LnCl3 and NaDC with various concentration and initial molar ratio are the same with one another. The resultants are all simple Ln(DC)3 complexes with the composition of Ln(DC)3? 6H2O.(3)Ideal models of the interaction of Ca2+ and Ln3+ with NaDC in vitro. have been suggested. The ability of Ln3+ destroying NaDC micelle is stronger than that of Ca2+ .
