基于碘离子对吐温８０－ＡｕＣｌ－４ 体系化学发光的强烈抑制作用，提出了一种测定痕量碘离子的新的化学发光分析法。方法的线性范围和检测限分别为１．２×１０－ ８～１．０×１０－ ６ ｇ／ｍ Ｌ和５．１×１０－ ９ ｇ／ｍ Ｌ碘离子。拟定的方法体系简单、选择性好，用于加碘食盐、加碘酱油和实际水样中碘离子的测定，结果满意。
Based on the strong inhibitory effect of iodine ion on the chemiluminescence of Tween 80-AuCl-4 system, a new chemiluminescence method for the determination of trace iodide ion was proposed. The linear range and the detection limit of the method were 1.2 × 10-8 ~ 1.0 × 10-6 g / m L and 5.1 × 10- 9 g / m L iodide respectively. The proposed method is simple and selective, and is suitable for the determination of iodine in iodized salt, iodized soy sauce and actual water samples. The results are satisfactory.
