In the present study, the complexing properties of ceftazidime with Fe(III) ions in aqueous solutions were characterized by UV-vis spectrophotometric and potentiometric methods. Using the UV-vis spectrophotometric method, the absorbance values for Fe(III) ions, a third-generation cephalosporin antibiotic (ceftazidime), and the Fe(III)-ceftazidime system were determined. Based on pH-metric studies, the value of the stability constant for the Fe(III)-ceftazidime complex was calculated.
在本研究中,采用紫外可见分光光度法和电位法研究了头孢他啶与 Fe(III)离子在水溶液中的配位性质。利用紫外可见分光光度法,测定了 Fe(III)离子、第三代头孢菌素抗生素(头孢他啶)和 Fe(III)-头孢他啶体系的吸光度值。基于 pH 滴定研究,计算了 Fe(III)-头孢他啶配合物的稳定常数值。
