The studies reported were aimed at finding a simple analytical method enabling quantitative determination of iodide in table iodised salt and in therapeutic iodide-bromide salts. The analytical procedure proposed is a modification of spectrophotometric method recommended in the Polish Standards. The method based on the reaction of iodide oxidation by sodium nitrite was validated by determining its precision, accuracy and linearity. Statistical analysis has shown that the coefficient of variation varies between 2.73 and 4.82%, recovery is from 99.17 to 101.83% and falls within the confidence interval for the mean recovery at the assumed level of significance. The method can be used for controlling the technology of table salt iodisation.
所报道的研究旨在寻找一种简单的分析方法，用于定量测定加碘食盐和治疗用碘溴盐中的碘化物。所提出的分析程序是对波兰标准中推荐的分光光度法的改进。通过测定其精密度、准确度和线性，验证了基于亚硝酸钠氧化碘化物反应的方法。统计分析表明，变异系数在2.73%至4.82%之间，回收率在99.17%至101.83%之间，且在假定显著性水平下的平均回收率置信区间内。该方法可用于控制食盐加碘工艺。
