| Abstract: | Two solvent Karl Fischer titration was applied to determine the water in ciprofloxacin hydrochloride, using methanol as the main solvent and water as a solubilizing agent. It is possible to determine the adherent and crystalline water in sample. The average recovery was 100.05%( RSD 0.25%). |
| Keywords: | ciprofloxacin hydrochloride two solvent Karl Fischer titration deter mination of water |
