Abstract
By designing a novel flow-through electrolytic cell, the Mn 3+ was firstly in situ generated electrochemically on the near surface of the platinum electrode by constant current oxidizing MnSO 4 in H 2SO 4 medium. It was then found that this Mn 3+ could oxidize sulfite, which was injected into the electrolytic cell, to produce the strong chemiluminescence (CL) emission signal. Based on this observation, a novel CL method for sulfite is developed in this paper. Under the optimum conditions developed, the CL emission intensity was linear with sulfite concentration in the range 3.0×1.0 −7 to 1.0×10 −4 mol/l ( r=0.9998). The detection limit was 8.0×10 −8 mol/l original concentration. The method was successfully used for the determination of SO 2 in the air sample.
