Popis: | In this work, the electrochemical oxidation of naproxen (NAP) was studied at an ultra-trace graphite electrode (UTGE). The cyclic voltammetry (CV) technique was used to determine the optimum conditions and the effect of pH on the electrochemical oxidation of NAP. Acetate buffer (pH 4.50) was selected as the support electrolyte due to obtaining the highest electronic signal increase during oxidation of NAP at UTGE. The differential pulse voltammetry (DPV) technique was performed for electrochemical determination of NAP. In the optimum conditions, the limits of detection (LOD) and quantification (LOQ) were determined to be 8.6610-8 M and 2.8810-7 M. In addition, the amount of NAP was determined in drug tablets. The recovery studies of NAP from the drug tablet were completed in order to check the accuracy and precision of the applied voltammetric method. Furthermore, the determination of NAP was performed with the high-performance liquid chromatography (HPLC) method. These two methods were compared in terms of accuracy, precision and recovery studies. |
