The electrocatalytic oxidation of sulfite in an acidic medium at a platinum-based, chemically modified glassy carbon electrode (Pt-Ch4E) was investigated. The electrode was characterized by voltammetry and flow injection, and applied to the determination of total and free sulfite by ion-exclusion ch
Nickel hexacyanoferrate (NiHCNF) film modified Al electrode prepared by simple and rapid electroless dipping procedure was used for the mediated oxidation of ascorbic acid. The anodic peak current observed in cyclic or linear sweep voltammetry was linearly dependent on the ascorbic acid concentratio
