前言铍的溶剂萃取,在分析分离中已有应用[1,2]。但是以磷酸三丁酯作萃取剂对铍的研究,文献中所见不多[3]。在此萃取过程中,往往要涉及到磷酸三丁酯对某些无机酸萃取的问题,但这方面的结论大体是一致的[4—10]。铍的提炼过程中,与杂质铝、铁的分离为一 Preface The beryllium solvent extraction has been used in the analysis of separation [1,2]. However, the use of tributyl phosphate as extraction agent for beryllium has not been seen in the literature [3]. In this extraction process, often involves the tributyl phosphate for some inorganic acid extraction problems, but the conclusions are generally consistent [4-10]. Beryllium refining process, with the impurities of aluminum, iron as one of the separation
