【摘要】 基于在碱性介质中头孢曲松钠对鲁米诺-K3Fe(CN)6化学发光体系的增强作用,建立了流动注射化学发光测定头孢曲松钠的新方法.测定范围0.1~400 mg/L,检出限0.06 mg/L,对0.2 mg/L头孢曲松钠溶液进行测定,相对标准偏差为1.6%,将其用于注射用头孢曲松钠粉针剂的测定,结果令人满意.更多还原

【Abstract】 Ceftriaxone sodium was determined by flow injection chemiluminescence,which is based on the strong enhancement effect of ceftriaxone sodium on Luminol-K3Fe(CN)6 chemiluminescence system in the alkaline medium.Under the optimum conditions,the determination range of method is 0.1~400 mg/L and the detection limit is 0.06 mg/L.The relative standard deviation for the determination of 0.2 mg/L ceftriaxone sodium is 1.6%(n=10).It has been satisfactorily applied to the determination of ceftriaxone sodium in the injections.更多还原
