Abstract

The present paper describes a simple method for the determination of uranium in uranium process stream solutions by reversed-phase liquid chromatographic method using C18 column, mixture of α-hydroxy isobutyric acid and methanol as eluent and flow-through spectrophotometer detector. This method has an advantage that interfering elements like rare-earth elements do not retain on the column and elute near the solvent peak thereby not interfering with uranium elution peak. Different eluents and parameters like pH, concentration of eluent are studied for the purpose. The spiking standard recovery was found to be more than 90 %. The developed method has been compared with other techniques and found to be in agreement.

测量铀提取设施工艺流溶液中铀含量的反相液相色谱法

本文介绍了一种利用 C18 色谱柱、α-羟基异丁烯酸和甲醇的混合物作为洗脱剂和流动分光光度计检测器的反相液相色谱法测定铀工艺流溶液中铀含量的简单方法。这种方法的优点是稀土元素等干扰元素不会保留在色谱柱上，而是在溶剂峰附近洗脱，因此不会干扰铀的洗脱峰。为此研究了不同的洗脱剂和参数，如 pH 值、洗脱剂浓度等。发现加标标准回收率超过 90%。将所开发的方法与其他技术进行了比较，结果表明两者是一致的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
