| 摘 要： | 研究了头孢曲松钠与Cd2＋、Ce3＋、Eu3＋、Tb3＋金属离子络合体系的紫外光谱和荧光光谱特征。结果表明,头孢曲松钠与金属离子的紫外光谱均发生不同程度的蓝移,甚至吸收峰消失,其吸光度除Cd2＋的升高,其余都下降;荧光强度也有明显的变化,加入Cd2＋、Eu3＋后头孢曲松钠的荧光猝灭,而加入Tb3＋后头孢曲松钠的荧光增强。在此基础上,采用头孢曲松钠与Cd2＋、Ce3＋、Eu3＋、Tb3＋金属离子物质的量之比分别为1∶0.6、1∶1、1∶0.6、1∶3合成络合物,并且利用红外光谱和元素分析对络合物进行验证。

| Abstract: | The spectra of ceftriaxone sodium with metal ions(Cd2+,Ce3+,Eu3+,Tb3+) were studied.The maximum ultraviolet absorbance wavelength of ceftriaxone sodium and metal ions was blue-shifted and even disappeared,while its absorbance was decreased after adding metal ions except Cd2+.The fluorescence intensity also changed obviously.The fluorescence was quenched by adding Cd2+ and Eu3+,while the fluorescence intensity became stronger after adding Tb3+.Under the optimum condition,the complexes were synthesized by usi... |
