摘要
采用紫外分光光度法测定了注射用头孢唑啉钠含量．头孢唑啉钠浓度为１０～３０μｇ／ｍＬ时呈很好的线性关系，回归方程：Ａ＝００２８９Ｃ－０００７４；ｒ＝０９９９９（ｎ＝５），平均回收率为９９８％，ＲＳＤ＝０２％．
An ultraviolet spectrometric method has been performed for the assay of cefazolin sodium for injection.When the concentration of the cefazolin sodium injection was 10～30 μg/mL the result and linearity were satisfactory.The regression equation: A=0 028 9 C-0 007 4;r=0 999 9(n=5). The average recovery from the sample was 99 8%. RSD =0 5%.
