摘要
铀是核能工业的关键元素。系统总结了近几年Davies-Gray法的不确定度评定和滴定条件对测定结果的影响和研究进展,从反应时间、搅拌速度、温度、湿度等方面进行梳理。重点介绍滴定结果偏低或偏高的原因和机理,旨在实现铀总含量的精密、准确测量,并提高方法的可靠性和适用性。
Uranium is a key element in the nuclear energy industry.The uncertainty assessment of the Davies-Gray method and the influence and research progress of titration conditions on the measurement results are systematically studied and summarized.It sorts out the reasons and mechanism for low or high titration results from the aspects of reaction time,stirring speed,temperature,humidity,etc.,aiming to achieve precise and accurate measurement of total uranium content and improve the reliability and applicability of the method.
