| Abstract: | Direct assay ofloxacin and metronidazole in compound ofloxacin ear drop solution with differential and sing-wave-length spectrophotometer at 293nm and 320nm. The average recovery are 99. 99% (RSD 0. 32% ) and 99. 91 % (RSD 0. 61 % ) respectively. This method direct assays ofloxacin and metronidazole in compound ofloxacin ear drop solution without separation. The method is simple and accurate and suitable for the quality controlling of the ear drop solution. |
