摘要:

头孢唑啉酸(cefazolin)为抗生素类药物,它的钠盐就是通常所说的先锋霉素. 我们通过共沉淀法合成了头孢唑啉酸与稀土元素Eu3+ 的固体配合物,并对其进行了光谱及波谱研究. 通过IR、1H NMR和13C NMR确定了配合物的配位点,并探讨了配位机理.

关键词: 头孢唑啉酸, 核磁共振, 稀土元素,  配合物

Abstract:

Cefazolin is an antibiotic, and sodium cefazolin is commonly known as  cephalexin. Solid complex of cefazolin with Eu3+ ion was synthesized in this study by the coprecipitation method. The complex synthesized was characterized by fluorescence spectroscopy, infrared spectroscopy (IR), thermal spectroscopy, scanning electron microscopic photographs and element analysis. The coordination sites of the complex and the mechanism of the complexing reaction were studied by  IR, 1H NMR and 13C NMR.

Key words: cefazolin, NMR, Eu3+, complex
