Summary: A DPV method using SPCEs was developed for the determination of SMX, showing a good detection limit (15 μg/L) and a wide linear range (50-600 μg/L) with good repeatability and reproducibility. The method was successfully applied to the analysis of a spiked tap water sample, demonstrating high reproducibility and good trueness. Additional considerations were made on the pH-dependent electrochemical oxidation of SMX and the role of the free terminal amino group in oxidation.

Summary: Corticosteroids are widely used drugs with various applications, but their adverse reactions necessitate monitoring in biological samples. In addition, considering their potential ecotoxicological effects, monitoring and reducing their presence in the environment may serve as a long-term solution to counteract their harmful effects. Therefore, the development of new, rapid, selective, and inexpensive electrochemical methods for determining corticosteroids in biological and environmental samples is crucial.
