Abstract
A method for the determination of iodate ion in table salt by differential pulse voltammetry was described.In the 1.0mol/L NaCl( pH = 12)solution,there was a sensitive differential pulse voltammetric peak of iodate ion on voltammograms when the pulse amplitude was 70mV and the pulse period was 0.2s.The peak potential was-1.30V (vs.Ag/AgCl).There was a good liner relationship between the peak current and iodate ion concentration in the range of 2.0 ×10-7～ 1.0 × 10-5 mol/L, and the correlation coefficient of 0.9995 was observed.The detection limit was 1.0 × 10-7mol/L This method had been applied for determination of iodate ion for the table salt sample and the average recovery was 100.7％.The results of CV test indicated that the electrochemical reaction of iodate ion at the electrode was irreversible.关键词
