^(129)I分析方法进展

Overview of Analysis Methods of (129)I

70年代以来 ,对 12 9I的研究迅速增加。这些研究采用了各种不同精密度和准确度的样品处理和分析方法。本文介绍和比较了 12 9I的各种分析方法 ,讨论了相关的样品处理过程。涉及的放化分析方法主要有中子活化和液体闪烁计数法等 ,非放分析方法主要有质谱和发射光谱分析法等。

There has been a rapid increase in the number of studies of 129 I since 1970's. These studies have employed a variety of pre treatment and analysis methods, with varying degrees of accuracy and precision. The relevant techniques are discussed and compared in this paper. The radioactive methods for determining 129 I are mainly NNA and liquid scintillation counting, while the non radioactive ones are mass spectrometry, atomic emission spectrometry, etc.
