摘要
采用原子吸收分光光度法测定注射用头孢唑林钠中钠的含量.光源为钠空心阴极灯,空气-乙炔火焰原子化器,波长330.2 nm.该方法的检测限为0.09％,定量限为0.31％,系统精密度RSD为0.68％(n=6),重复性RSD为0.62％,中间精密度RSD为1.49％,线性范围为0.200 3～0.400 7 mg/mL(r=0.999),平均回收率为100.8％(RSD为0.91％).该方法专属性、精密度、线性、耐用性等参数符合要求,可用于测定注射用头孢唑林钠中钠的含量,准确度和灵敏度高.
Abstract
The research is dedicated to determining the content of sodium in cefazolin sodium for injection by atomic absorption spectrophotometry.Atomic absorption spectrophotometry was used,the light source was a sodium hollow cathode lamp,the atomizer was an air-acetylene flame atomizer,and the wavelength was 330.2 nm.The detection limit of this method was 0.09％,the quantitative limit was 0.31％,the system precision RSD was 0.68％(n=6),the repeatable RSD was 0.62％,the intermediate precision RSD was 1.49％,and the linear range was 0.200 3～0.400 7 mg/mL(r=0.999).The average recovery rate was 100.8％(RSD was 0.91％).The specificity,precision,linearity and durability of this method meet relevant requirements.This method can be used to determine the content of sodium in cefazolin sodium for injection with high accuracy and sensitivity.
