| Abstract | ||||
| A simple, rapid, and reliable direct spectrophotometric method for the determination of ciprofloxacin has been proposed and validated to overcome the lack of comprehensive reports on its estimation under different chemical conditions. Ciprofloxacin (CIP) was reported to be a well-known broad-spectrum fluoroquinolone antibiotic with activity against both Gram-positive and Gram-negative bacteria pathogens. The spectroscopic analysis of CIP includes the impact of solvent, ionic strength, pH, and temperature on the intrinsic spectroscopic features of CIP. A linear calibration curve was constructed with a correlation coefficient of 0.99 over concentration values (5-30 mg/l). The molar absorptivity (ɛ) and mean recovery were investigated to be 22.2 x 103 L.mol-1.cm-1 and 99.2%, respectively. The limit of detection (LOD) and quantification (LOQ) were assessed in accordance with ICH guidelines. The developed approach has been successfully validated for simultaneous determination of Ciprofloxacin, as evidenced by the high recovery values. | ||||
