Description
The detection of pharmaceutical contaminants in aquatic environments, including wastewater and natural water bodies such as rivers, lakes, and seas, is essential for safeguarding environmental health and ensuring water quality. Pharmaceuticals, often incompletely metabolized by humans and animals, persist in the environment and pose risks to ecosystems due to their bioactivity and potential for accumulation. This study investigates the application of polymer-modified screen-printed graphene electrodes (SPEs), specifically those modified with polyvinylidene fluoride (PVDF), for the sensitive detection of diclofenac and doxorubicin as widely used pharmaceutical compounds. Electrochemical analysis was performed using cyclic voltammetry to evaluate the performance of the modified electrodes and compare it to the commercial one. The PVDF modification enhanced sensitivity, stability, and reproducibility through improved adsorption and hydrophobic interactions for both pharmaceutical compounds. These results highlight the potential of PVDF-modified graphene electrodes as cost-effective and rapid tools for monitoring pharmaceutical residues in diverse aquatic environments, contributing to pollution management and environmental protection efforts.
