用零交导数分光光度法测定氧氟沙星葡萄糖注射液中氧氟沙星的含量。以 2 78 4nm (峰 )处的半振幅为定量依据 ,可排除注射液中葡萄糖分解产物对测定的干扰。该方法平均回收率为 10 0 16 % ,RSD =0 4 7%。方法简便、快速、准确。
Determination of Ofloxacin in Ofloxacin and Glucose Injection by Zero Cross Derivative Spectrophotometry. The half amplitude at 2 78 4 nm (peak) was used as a quantitative basis to exclude interference from the glucose decomposition products in the injections. The average recovery of this method was 10% to 16% with RSD = 0 47%. The method is simple, fast and accurate.
