目前对矿物岩石中的铀,所采用的分析技术中,化学分析为普遍采用的办法。化学分析又是最准和应用最广泛的分析方法,因此化学分析占着十分重要的地位。近几十年来,随着分析化学的进展,已出了许多新的方法、新的特效性的试剂和灵敏度更高的仪器,并且目前多向快速分析方向发展着。用化学办法分析矿物岩石中的铀,同分析矿物岩石中其它元素一样,最常采用的有下列几种: (一)重量法虽然分析速度较慢,操作手续又繁杂,但准确度高,有时仍然应用。该法主要是用于分析化合物中的铀、合金中的铀、浓縮物中的铀和一些溶液中的铀等;尤其是作为方法的检查,以及标准溶液的标 The current analysis of uranium in mineral rock, the analytical techniques used, chemical analysis is commonly used approach. Chemical analysis is the most accurate and the most widely used analytical methods, chemical analysis therefore occupies a very important position. In recent decades, with the progress of analytical chemistry, many new methods have been developed, new special effects reagents and instruments with higher sensitivity, and the direction of multi-direction rapid analysis has been developed. Chemical analysis of uranium in mineral rock is the same as the analysis of other elements in mineral rock. The most common ones are the following: (1) Although the gravimetric method is slow in analysis and complicated in operation, it has high accuracy and sometimes Still apply. The method is mainly used for the analysis of uranium in compounds, uranium in alloys, uranium in concentrates and uranium in some solutions; especially as a method of inspection and standard solution standards
