Abstract
Pantoprazole, a proton pump inhibitor drug that is used to control stomach acid. The main role of this drug in the body is acid stable. Determining and measuring the drug in water and wastewater treatment and reducing toxicity in biological fluids is of great importance and identification of a variety of methods have been presented. A solid phase extraction sample preparation technique is useful, fast and simple. In this study, the performance of the modified nanoparticles (Fe3O4) with a cationic surfactant Cetyl trimethyl ammonium bromide (CTAB) as an adsorbent for pantoprazole drug extraction from real samples was analyzed. The parameters affecting the extraction process were investigated and optimized in terms of the drug determined by using UV-visible spectroscopy technique. The parameters affecting the extraction efficiency such as the pH of the solution, the amount of CTAB, extraction time, the amount of adsorbent (Fe3O4), the type and amount of detergent (solvent), desorption time, were studied and optimized. Under optimal conditions, the calibration curve was linear over the concentration ranges of 0.1-1.2 µg/ml for pantaprazole. Proposed method for measuring pantoprazole drug in aqueous samples and human plasma applied and satisfactory results were obtained . All procedures showed that the method for extraction of pantaprazole of real samples, was fast and efficient
