%X The interference from sulphide and dithionite on the electrochemical analysis of sulphite on platinum in alkaline fresh water has been examined in the present study. Cyclic voltammetric experiments with a rotating disc electrode were used to examine how these compounds affect kinetics and the diffusion properties of sulphite. The reaction rate for the oxidation of sulphide was slow. Chronoamperometric experiments were therefore used to study this reaction. The results show that the linear relationship between the current density and the sulphite concentration that was found in a pure sulphite solution could not be obtained when sulphide and dithionite were also present in the solution.
