摘要
采用FTIR、XRD、UV-Vis、^(13)C NMR等以及脱质子计算方法进行表征分析,研究了Zr(Ⅳ)与苦杏仁酸的相互作用。结果表明:在室温及pH≈0.5条件下,Zr(Ⅳ)与苦杏仁酸上的羟基和羧基都发生了配位作用,且Zr(Ⅳ)与—OH、—COOH的配位数都为1,按双齿配位螯合成五元环配合物。
We have studied the interaction between zirconium sulfate and mandelic acid by means of characterization methods, such as FTIR, XRD, UV-Vis,^（13）C NMR,deproton calculation and so on.The results showed that, at room temperature and under the conditions of pH ≈0.5,zirconium sulfate can coordinate with the hydroxyl and carboxyl groupson bittermandelic acid. The coordination number of Zr^（4＋） with —OH and —COOH are 1. And synthesis of five membered ring complexes by double tooth coordination chelate.
