摘要

本评论总结了使用激光/LED-荧光分析仪对天然水中的铀进行可靠分析的各种因素。无论是生活废水还是天然水,都不可能完全彻底地保存样品。样品采集后,物理化学和生物变化不可避免地会继续发生。因此,需要使用移动地球化学实验室对水样进行现场/快速分析,最好能在当天完成。激光诱导荧光测定法/脉冲发光二极管荧光测定法是一种有据可查、灵敏度高且用途广泛的技术,可用于测定水样中微克/升水平的铀含量,但事实上,由于水样种类繁多,包括盐水、各种腐殖质和氟化物含量在内的总溶解盐分各不相同,尤其是在炎热干旱地区,以及由于实际上不可能保存天然水样,因此这项技术更具挑战性。因此,样品采集和分析之间的时间间隔是在炎热干旱地区进行可靠铀分析的最关键因素。水样中的高 TDS 会导致主要阳离子和阴离子以及铀含量随样品采集和分析之间的时间间隔而发生较大变化。此外,此类基质也没有经过认证的参考材料来交叉检验/确保结果的可靠性。

Challenges for reliable analysis of uranium in natural waters using laser-induced fluorimetry/LED-fluorimetry in the presence of fluoride and diverse humic substances in hot arid regions and future advances – review

The presence of fluoride and diverse humic substances in arid regions results in changes in the content of uranium, major cations and anions if there is a time interval between sample collection and analysis, and this disrupts the reliable analysis of uranium in natural waters using laser/LED-fluorimetry, and this is discussed in this review. Complete and unequivocal preservation of samples, whether domestic waste water or natural water, is a practical impossibility. The physico-chemical and biological changes continue inevitably after sample collection due to changes in dynamic equilibrium. Thus, the use of a mobile geochemical laboratory for on the spot/quick analysis of water samples, preferably on the same day, is required. Laser-induced fluorimetry/pulsed LED-fluorimetry is a well documented, highly sensitive, and versatile technique for the determination of uranium in water samples at μg L−1 levels. This is made more challenging due to the wide variety of types of water samples, which differ in total dissolved salts found, and these include saline water, diverse humic substances and fluoride content, especially in hot arid regions as well as due to the practical impossibility of preserving natural water samples. Therefore, it is the time interval between sample collection and analysis that is the most critical factor for the reliable analysis of uranium in hot arid regions. A high level of total dissolved solids (TDS) in water samples results in greater variation in the major cations and anions, and uranium content with respect to the time interval between sample collection and analysis. Moreover, there is no availability of certified reference materials for such matrices to cross-check/ensure the reliability of the results.
