摘要

Mesoporous materials are described by their relatively high surface areas and pore volumes. They possess uniform channels within nanometer range. These materials have numerous applications in catalysis, separation and many other fields. The qualitative and quantitative determination of antibiotic drugs, i.e., ciprofloxacin and cefixime has clinical and analytical importance due to their broad spectrum of antimicrobial activity and stability. Both antibiotic drugs are orally active and have excellent activity against different pathogens. It is for the first time that we have developed an analytical method for the simultaneous analyses of both drugs using?a newly developed p -morpholinomethylcalix[4]arene ( p -MC4) mesoporous silica-based HPLC column (15?×?3?mm I.D.). Furthermore, separation of these two components was carried out using isocratic elution of methanol and 0.1% aqueous formic acid (70:30 v/v) with flow rate of 1?ml min_(?1)at retention time of 2.71 and 4.21?min and retention factor 1.85 and 1.19 for ciprofloxacin and cefixime, respectively; while total run time was 5?min. The developed method was repeatable with a relative standard deviation (RSD) of 0.90–2.08% for antibiotic drugs. The limits of detection and quantification of ciprofloxacin and cefixime were obtained within the range of 0.152–0.801 and 0.40–1.23 μg?mL_(?1), respectively. The method is highly applicable, rapid, simple, very reproducible and accurate for the separation and determination of antibiotic drugs.
