本文采用卡尔曼滤波分光光度法,不需预先分离,即可直接测定复方氧氟沙星滴耳液中氧氟沙星和甲硝唑的含量。氧氟沙星和甲硝唑的平均回收率分别为99.29%和100.2%,相对标准百分偏差分别为0.53%和0.72%。该法简单、快速、准确。
In this paper, Kalman filter spectrophotometry, without prior separation, you can directly measure the compound ofloxacin Ear Drop ofloxacin and metronidazole content. The average recoveries of ofloxacin and metronidazole were 99.29% and 100.2%, respectively, with relative standard deviation of 0.53% and 0.72%, respectively. The method is simple, fast and accurate.
