摘要

介绍了用加速器质谱法（AMS）分析129I的研究。测定Alpha Aesar KI产品10978（纯度为99.995%）为129I/127I = 1.6x10-14，适合作为载体和背景材料。氯仿和正己烷以碘为载体萃取海水中的碘，表明正己烷具有优势；提取率80%。一种“无碘载体”的提取方法，将海水中的其他天然卤化物作为载体共沉淀，发现具有>；提取率98%。在3个AMS实验室测量的海水129I浓度结果平均一致10%，与20年前的上一次比较相似。相反，ICP-MS测量的127I浓度仅在两个实验室之间具有良好的一致性。采用载体和无载体两种方法处理的样品的AMS结果计算出的海水127I浓度与ICP-MS测量结果一致，提示了127I浓度测量的替代方法。本文还介绍了8个韩国沿海海水样本的数据。

129I analysis of seawater at KIST: Carrier and carrier-free extraction techniques, an inter-laboratory comparison of results, and an alternative to ICP-MS 127I concentration measurements

Studies for ¹²⁹I analysis by accelerator mass spectrometry (AMS) are presented. Alpha Aesar KI product 10978 (99.995 % purity) was measured to have ¹²⁹I/¹²⁷I = 1.6x10^-14, suitable for use as carrier and background material. Iodine extraction from seawater using chloroform and n-hexane with iodine carrier showed hexane to have advantages and > 80 % extraction yield. An “iodine carrier-free” extraction method, co-precipitating other halides native to the seawater as carriers, was found to have > 98 % extraction yield. Results of seawater ¹²⁹I concentrations measured at 3 AMS laboratories averaged 10 % agreement, similar to the last comparison 20 years ago. Conversely, ¹²⁷I concentrations measured by ICP-MS were in good agreement between only two laboratories. Seawater ¹²⁷I concentrations calculated from AMS results for samples treated using both carrier and carrier-free methods were in agreement with ICP-MS measurements, suggesting an alternative for ¹²⁷I concentration measurements. Data for 8 Korean coastal seawater samples are also presented.

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
