Abstract
Glyphosate is a widely used herbicide applied across a large range of agricultural practices, and its extensive use has raised concerns due to its environmental persistence and the toxicity of its main metabolite, aminomethylphosphonic acid (AMPA). Ensuring compliance with strict regulatory limits requires reliable detection at very low concentrations, down to 1 µg/mL. This work examines the key elements needed to develop a robust electrochemical method for glyphosate quantification, with emphasis on electrode materials, surface stability, and the feasibility of direct electrochemical oxidation. Direct oxidation is particularly important because it enables the use of simple, unmodified electrode surfaces, improving robustness and reducing the need for complex functionalisation steps. The results define the critical parameters that could enable accurate, field-deployable detection.
