The correspondent mathematical model analysis confirms this process's efficiency for furfural and lactic acid determination in a mildly acidic and neutral medium by a cathodic determination to propyleneglycol and furfuroic alcohol. Considering that both the compounds and their reduction products are less ionized in acidic media, cathodic reduction tends to be more efficient than anodic electrooxidation. © 2023 by the authors.eninfo:eu-repo/semantics/openAccessElectrochemical SensorFurfuralLactic AcidStable Steady-StateVanadium (Iii) OxyhydroxideArticle136N/AQ3
