紫外分光光度法测定氧氟沙星滴眼液中氧氟沙星的含量,以0.1mol/L 醋酸为溶剂,测定波长293nm,吸收系数(E_(10m)~(1%))为876,测得平均回收率为99.9%,CV=0.36%(n=5)。滴眼液附加剂对测定无干扰。
The content of ofloxacin in ofloxacin eye drops was determined by UV spectrophotometry. The concentration of ofloxacin was determined by the method of 0.1 mol / L acetic acid at a wavelength of 293 nm with absorption coefficient (E_ (10m) ~ (1%)) of 876. The average recovery was 99.9%, CV = 0.36% (n = 5). Eye drops additives for the determination of non-interference.
