摘要
目的研究我国水源型高碘地区水中碘的存在形态。方法采集部分高碘地区的水样,采用碘-淀粉分光光度法和高效液相色谱等离子体质谱法鉴别水中碘的形态和测定水碘含量。结果在172份水样中,161份以碘离子(混含少量的碘分子)形态存在,10份以碘酸根和碘离子混合形态存在,1份以单纯的碘酸根形态存在。结论我国高碘地区存在碘离子和碘酸根两种形态的高碘水源,碘离子是主要存在形态,其次是碘离子和碘酸根共存形态,单纯的碘酸根形态较少。在碘离子和碘酸根共存的水源中,碘酸根为主要形态。尚未发现以高碘酸根形态存在的水源。
Objective To understand the forms of iodine in water in areas with rich iodine in water in China.MethodsI2-Starch Spectrophotometry and high performance liquid chromatography-inductively coupled plasma mass spectrometry（HPLC-ICP-MS） were used to identify the forms of iodine and measure the iodine level in water samples taken from some areas with rich iodine in water in China.Results Among 172 water samples detected,iodine exists in the form of iodide（with a limited amount of iodine molecules） in 161 water samples,both iodate and iodide in 10 water samples and iodate in 1 water sample.Conclusion In some areas with rich iodine in water in China,iodine mainly exists in the form of iodide,followed by both iodide and iodate,iodate form is rare.No sample was found to contain periodate.
