Abstract
A Simple technique has been developed for electrochemical oxidation and determination of nimesulide (NIM) drug-using voltammetric techniques in phosphate buffer solutions. The modified sensor showed good stability, sensibility, and enhancement in the peak current with good reproducibility. Based on the variation of parameters and their results, the heterogeneous rate constant value was also calculated. The proposed sensor can be utilized for the analysis of the drug in biological and pharmaceutical samples with good recovery values. A suitable electrooxidation mechanism was proposed. The proposed technique was successfully employed for the determination of NIM in biological samples with good recovery results.
