Abstract
An improved method tor the coulometric assay of uranium and uranium oxide has been developed based on the electrogeneration of Ti(III) in HSO, using Fe(II) as a catalyst. The endpoint is determined amperometrically. Hydrogen peroxide is used as the oxidant in the dissolution of the uranium to avoid interferences from nitrate. The precision of the method as indicated by the standard deviation of an individual observation ranged from 0.008 weight percent for the analysis of the metal to 0.02 weight percent for the analysis of the oxides.
摘要
基于在硫酸中以亚铁离子为催化剂通过电解产生三价钛，已开发出一种改进的库仑法测定铀及氧化铀的方法。终点通过安培法测定。用过氧化氢作为铀溶解过程中的氧化剂以避免硝酸盐的干扰。该方法的精密度，以单次观测的标准偏差表示，对于金属分析为0.008重量百分比，对于氧化物分析为0.02重量百分比。
