尿碘水平能较好的反映人体近期的碘营养状况 ,是碘缺乏病病情监测及其预防的重要生化指标[1 ] 。近几年来 ,微量碘的测定方法发展较快 ,许多分析方法如气相色谱法、质谱仪分析法、原子吸收分光光度法和化学发光法等均有应用 ,但是 ,由于这些方法在灵敏度、准确性、精密度、抗干 Urinary iodine levels can better reflect the body’s recent iodine nutrition status, is iodine deficiency disease monitoring and prevention of important biochemical indicators [1]. In recent years, the determination of trace amounts of iodine has developed rapidly, and many analytical methods such as gas chromatography, mass spectrometry, atomic absorption spectrophotometry and chemiluminescence have been used. However, due to their sensitivity and accuracy , Precision, anti-dry
