A Review on Analysis of Natural Uranium Isotopes and Their Application

“…MC-ICP-MS를 이용한 우라늄 동위원소 분석을 위해서 일반적으로 이온교환수지(ion exchange resin)를 활용한 이온 크로마토그래피(Ion Chromatography)을 통해 우라 늄을 분리해 낸다. 이러한 우라늄의 분리는 실험 목적에 따라 세부 프로토콜이 다양하게 개발되어 활용된다(e.g., Chen and Wasserburg, 1981;Escareño-Juárez et al, 2019;Hiess et al, 2012;Horwitz et al, 1992;Stirling et al, 2005;Tissot and Dauphas, 2015;Weyer et al, 2008;Zhang et al, 2021) 에서 공급되는 물질들이 사용되며, CRM-112a, CRM-129a, CRM-145, SRM-950a, IRMM-184, REIMP-18a 등 이 존재한다 (Cheng et al, 2013;Goldmann et al, 2015;Hiess et al, 2012;Richter et al, 2010;Stirling et al, 2007;Tissot and Dauphas, 2015;Weyer et al, 2008). 이 중 가 장 널리 활용되는 CRM-112a 표준물질의 238 U/ 235 U 비의 절대값은 137.849 ± 0.0079이며, 연구에 따라 137.829 ± 0.022 에서 137.843 ± 0.008의 분석값이 보고되었다 (Cheng et al, 2013;Goldmann et al, 2015;Hiess et al, 2012;Tissot and Dauphas, 2015).…”

Effect of humic acid derived from leonardite on the redistribution of uranium fractions in soil

“…It is present in abundance in the earth’s crust, and the average crust content of U is 2.6 mg/kg ( Rankin, 2008 ). Most rocks typically contain 0.4–3.7 ppm of U ( Escareño Juárez et al, 2019 ). In nature, there are three isotopes of uranium: U 238 (99.275%), U 235 (0.72%), and U 234 (0.054%), and depleted uranium (DU) usually contains 0.3% of U 235 (or less).…”
