THE INVESTIGATION OF THE VIABILITY OF THE Pt ELECTRODE IN SULPHITE CYCLIC VOLTAMMETRIC ASSAY
نویسنده
چکیده
This paper aims at the study of Pt electrode ability to act as working electrode in cyclic voltammetric sulphite assay. The analytical signal is represented by the intensity measured for the voltammetric peak, that corresponds to analyte anodic oxidation. The measured peak intensity depends linearly on sulphite concentration within the range 0.031 g/L – 4 g/L. The assay is characterized by a limit of detection of 12.4 mg /L, a relative standard deviation of 2.74%, and the process proved controlled by the analyte diffusion to the electrode.
