摘要
本文研究了用紫外分光光度法测定诺氟沙星眼药水中诺氟沙星的含量,选用pH5.8磷酸盐缓冲液为溶剂,测定波长315nm。吸收系数(E_(1cm)^(1%))为393,测得平均回收率为99.8%,CV=0.43%(n=5)。眼药水附加剂对测定无干扰。
The ultraviolet spectrophotometry for determing the content of norfloxacin in the ophthalmic solutionhas been developed.Norfloxacin was analyzed at 315nm,the average recovery was 99.8%,the coefficientof variation was 0.43%(n=5). Results of experiments showed that ultraviolet spectrophotometry was anavailable method for the determination of norfloxacin eye drops.
