用三烷基（C6-C8）氧膦（TRPO）萃取-液体闪烁计数法测定水溶液中微量α核素的研究
THE STUDY ON DETERMINATION OF TRACE a-NUCLIDE CONTENTS IN AQUEOUS SOLUTION WITH TRPO SOLVENT EXTRACTION-LIQUID SCINTILLATION COUNT METHOD
【摘要】 本工作用三烷基氧膦（TRPO）作萃取剂,二甲苯为溶剂,2.5-二苯基噁唑为闪烁体研究了TRPO及杂质元素的猝灭效应,结果表明萃取-液体闪烁计数法用于测量大量杂质元素及氨羧络合剂中的233U,239Pu,241Am微量α核素具有简便、迅速,灵敏度高等优点。
【Abstract】 The solvent extraction-liquid scintillation count method has been studied, TRPO has been used as the extractant, dimethylbenzol as the diluent, 2.5-di?phenyloxazole as the scintillator. The quenching effects caused by TRPO or other impurity elements have been studied. The results appear that this method can determine trace a-nuclide contents (238U, 239pu, 241Am2) with a large quantity of impurity elements and amino-polycarboxylic acid. The determination can be done simply, quickly and sensitively.
