An automatic potential method have been developed to measure totaliodine in seawater by glassy carbon electrode. It is based on nearlystraight variations in potential of working electrode in cerium (Ⅳ)-arsenic (Ⅱ) system containing iodine as a catalyst, and the potentialvaring speed is directly proportional to the iodine concentration.Experimental results show that chief interference in iodine measurementwould arise from chloricion, but not from bromicion, and therelationsof potential varing speed with iodine concentration are given by followingexperimental equations:(dE/dt)_T=(30.2)=(0.0055+0.00014S) [I]+0.0025S+0.0033(dE/dt)_-(20.?)=(0.0029+0.00007S) [I]+0.00069S+0.0010 Three quantitative methods according to calibrated curve, simple st-andard addition and multiple standard additions are used for determiningiodine, among others the multiple standard additions method is most acc-urate, the accuracy and recovery for the sample containing 5.0μg of iodine/1are 0.15μg of iodine/1 and 101±5% respectively. The potential fixed m-ethod is simple, rapid and convenient in field measurement.

本文采用玻璃石墨电极自动电位测量-记录装置测定了海水中的总碘量。该方法基于铈(Ⅳ)-砷(Ⅲ)体系被碘催化时的电位变化几呈线性,而且变化速度与碘浓度成正比。实验证明,海水中氯离子是主要干扰性物质,溴离子影响较小。电位变化速度可以表示为(dE/dt)_(T=30·C)=(0.0055+0.00014S)[Ⅰ]+0.0025S+0.0033 (dE/dt)_(T=20·C)=(0.0029+0.00007S)[Ⅰ]+0.00069S+0.0010 为了减少误差、简化操作,可以在每次测定时原位确定本底值,并且采用标准添加法进行定量。多次标准添加作图法可以获得比较准确可靠的数据。简单的固定电位计时法适于现场分析,并能得到满意结果。该方法检出下限为0.2微克碘/升,对于含有50微克碘/升的海水样品,经十倍冲稀后测定,准确度为0.26微克碘/升,回收率101±5%。木文所提出的电测技术具有灵敏、快速、准确、自动和简单等特点,适于微量样品分析和现场检测。在催化分析中可望得到新的实际应用。

In this work, 3,5-L-diiodothyronine as a starting material, 125I-L-triiodothyronine (125I-T3) and 131I-L-triiodothyronine (131I-T3) are prepared, and the specific activity of 125I-T3 is measured by self-displacement and from the standard curve obtained by 131I-T3 for the radioimmunoassay of 125I-T3. The specific activity of Na125I solution can be calculated from that of 125I-T3. This is a new method for the determination of the specific activity of radioiodine. Meanwhile, the total iodide content of the Na125I, Na131I solutions is measured via an iodide selective electrode, and the radioactivity of the Na125I, Na131I solutions via a calibrated 4π-ionazation chamber respectively. Thereby the specific activities of radioiodines can be calculated. The results obtained by different methods agree fairly well. The abundances of iodine-125 and iodine-131 in the Na125I and Na131I solutions are about 50% and 6% respectively. The sources of iodine in the samples are also discussed.
