英文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合物 .利用红外光谱( FTIR)、元素分析、 ICP分析及 X射线粉末衍射谱,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响产物的组成和结构 .说明虽然 Ln3+与 Ca2+有相似之处,但它们与 NaDC的作用却有很大差别 .; 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: ii) The structure and composition of resultants vary with the concentration and initial molar ratio of CaCl2 and NaDC, The resultant can be simple Ca(De)(2) complex with the composition of Ca(DC)(2). 3H(2)O 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 LnCl(3) 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). 6H(2)O, (3)Ideal models of the interaction of Ca2+ and Ln(3+) with NaDC in vitro. have been suggested. The ability of Ln(3+) destroying NaDC micelle is stronger than that of Ca2+.; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 3; 10; 873-878; 16
