| 摘 要： | 报道了一种测定碘酸根离子含量的方法。在 0 .5mol/L Na Cl介质中 ,碘酸根离子在汞膜电极上于 - 1 .2 5V( vs.Ag/Ag Cl)左右产生一灵敏的方波伏安峰 ,峰高与碘酸根离子浓度在一定范围内呈良好的线性关系 ,方法检出限为1 .0× 1 0 - 7mol/L,已用于加碘食盐中碘酸根含量的测定。

| Abstract: | In a 0.5 mol/L NaCl solution a sensitive square wave voltammetric peak of iodate at mercury film electrodes at -1.25V( vs .Ag/AgCl) was found. The peak height had linear relationship with the concentration of iodate. The method was used to determine the trace amount of iodate in iodized salt with satisfactory results. |
