| 摘 要： | 目的:建立测定人尿样中碘离子浓度的离子色谱法。方法:采用离子色谱,在IonPacAS7柱上,用50mmol/L的硝酸为淋洗液测定尿液中碘离子的含量。检测方式为直流安培检测,工作电极为Ag电极,参比电极为Ag/Agcl电极。结果:碘离子浓度检测线性范围为50～1000μg/L(r=0.9998),平均回收率为95.8%～97.0%,相对标准偏差为2.6%～3.7%;测得的正常人尿碘浓度为100～300μg/L。结论:该方法稳定、准确、快速,可用于实际样品的测定。

| Abstract: | OBJECTIVE:To establish ion chromatography for the determination of iodine ion concentration in human urine.METHODS:Iodine ion concentration was determined using chromatography of ions,the determination was performed on Pac AS 7 column with50mmol/L nitric acid as the elutriant.The detection was by means of DC amperometer detector with Ag as working electrode and Ag/AgCl as reference electrode.RESULTS:The linear range of iodine ion concentration was 50～ 1000μg/L(r=0.9998),the average recoveries were 95.8%～97.0% with RSD at 2.6%～3.7%.The iodine ion concentra-tion in health adults was detected at 100～300μg/L.CONCLUSION:The established method is stable,accurate and fast,and suitable for the determinate of iodide in human urine. |
