本文采用紫外分光光度法于325nm波长处测定注射用青霉素钠的含量在1.25一15ug/ml浓度范围内符合Beer定律。本法稳定性好;平均回收率100.4％(n=5)CV=0.49％
In this paper, UV spectrophotometry at 325nm wavelength determination of penicillin sodium injection in the content of 1.25 a 15ug / ml concentration range in line with Beer’s law. This method has good stability; average recovery rate 100.4% (n = 5) CV = 0.49%
