摘要
为在由有电气化学的预告的处理的离子层析(IC ) 的尿的氟的符号和碘的同时的决心的一个新方法被开发了。预告的处理在新奇电气化学的 oxidation– 被执行；中立化设备(EOND ) ，在哪个样品的碘化物被氧化到以碘处理和碱的消化样品答案被抵销。在优化条件下面，察觉的限制(LOD， S/N = 3 ) 是 2.5 μ；为氟化物的 g/L 和 20 μ；为以碘处理的 g/L 分别地。恢复在 93 – 的范围； 102% 为氟化物和 86 –； 98% 为以碘处理。
A new method for the simultaneous determination of fluorine and iodine in urine by ion chromatography （IC） with electrochemical pretreatment has been developed. The pretreatment was performed in a novel electrochemical oxidationneutralization device （EOND）, in which iodide of the sample was oxidized to iodate and the alkaline digestion sample solution was neutralized. Under the optimized conditions, the limits of detection （LOD, S/N = 3） were 2.5 μg/L for fluoride and 20 μg/L for iodate, respectively. The recoveries were in the range of 93-102% for fluoride and 86-98% for iodate.
