中文摘要: 从化学分析(破坏性分析)和非破坏性分析两个方面入手系统地介绍了岩石矿物中铀钍的分析方法。湿法化学法部分着重介绍了岩石矿物中铀钍的化学分析方法原理、特点和应用范围。常用的化学分析包括重量法、比色法、容量法、光度法、激光荧光法、极谱法、光谱法、α能谱法和先进的质谱法等;随着新仪器手段的发展进步,先进的化学分析手段特别是电感耦合等离子质谱法(ICP-MS)如雨后春笋般普及推广,其它传统湿法化学分析应用越来越少。
Abstract:The principles and characteristics of the analytical methods for determination of uranium and thorium in rocks and minerals are systematically introduced mainly from two aspects: chemical analysis (destructive) and non-destructive analysis. In wet chemical method section, the focuses are the introduction of the principles, characteristics and application scope of the chemical analysis methods. The Commonly used chemical analysis methods include gravimetric method, colorimetry, titration, spectrophotometery, laser-induced fluorescence method,polarography, spectroscopy, alpha spectroscopy and advanced mass spectrometry, etc. With the development of new instruments, especially, when the applications of advanced chemical analysis technique like inductively coupled plasma mass spectrometry (ICP-MS) emerge like bamboo shoots after a spring rain, the traditional wet chemical analysis methods will be less and less used.
