| Abstract: | imultaneous equation spectrophotometry was employed to determine the content of metronidazole and chlo-ramphenicol in acne liniment. The wavelengths used were 278. onm and 320. 0nm. Average recoveries were100. 3%, RSD=0.2% and 100.2%, RSD= 0. 4%,respectively. The method was simple and accurate. |
