Selenium oxide nanostructure-based electrodes for rapid and simultaneous electrochemical determination of oxalic and ascorbic acids in food matrices

RNRania M. NeedaHIH. IbrahimAYAhmed F. A. Youssef

Key Points

  • The central aim is to develop a sensing strategy for the simultaneous detection of ascorbic and oxalic acids.
  • Utilized a selenium oxide-modified carbon paste electrode (SeO2 @CPE)
  • Engaged a portable potentiostat for electrochemical measurements
  • Focused on simultaneous oxidation of ascorbic and oxalic acids
  • Successfully quantified ascorbic and oxalic acids in food matrices
  • Demonstrated rapid detection capabilities with high accuracy
  • Established effectiveness of SeO2 @CPE for electrochemical analysis

Abstract

An electroanalytical sensing strategy was developed for the simultaneous oxidation and quantification of ascorbic acid (AA) and oxalic acid (OA) using a SeO 2 -modified carbon paste electrode (SeO 2 @CPE) integrated with a portable potentiostat.
