摘要
根据稳定悬浊液的吸光特性,建立了新双波长分光光度法测定头孢氨苄含量。结果该法在8~24μg/ml浓度范围内线性良好,r=0.9998,平均回收率99.42%,RSD=0.39%。结果表明:所用计算模型稳定,不受操作的环境条件影响,方法简便,测定准确。
In accordance with the light absorbing property of stable suspension,the method for determinating the content of cefalexin capsule by new double wavelength spectrophotometry was established.The used calculating model was stable without influence of surrounding operation conditions.This method was easy to operate with accurate determination and good linearity in the density range 8~24μg/ml r=0.9998.Average rate of recovery=99.42%.RSD=0.39%.
