The nitrite-rodanide method was suggested to determine the content of iodine in food. It was shown that this method, provided the exposure of the test solutions during colorimetry was appropriately chosen, enables the determination in an aliquot of 0.5 g of both low and high (2-600 microgram/100 ml) concentrations of iodine. The determination of high concentrations can be realized by an ordinary diluting of the solutions under colorimetry.
有人建议用亚硝酸盐-罗丹宁法测定食品中的碘含量。结果表明，该方法只要比色时测试溶液的曝光时间选择得当，就能在0.5克样品中测定低浓度和高浓度（2 - 600微克/100毫升）的碘。高浓度碘的测定可通过比色时对溶液进行常规稀释来实现。
