近年来由于铍在原子能和火箭技术中找到了新的用途,因之铍的分析分离问题已引起了人们极大的兴趣。本文拟就近十年来有关溶剂萃取分离铍的方法的研究作一综述。螯合物体系β-二酮类:铍与β-二酮类的乙酰丙酮(简称 AA)、苯酰丙酮、二苯酰甲烷、2-麸酰-苯酰甲烷、2-麸酰-2-噻吩甲酰甲烷等能形成稳定的螯合物。尤特(vanUitert)等已测得了这些螯合物的生成常数。另外铍与硫茂羧基三氟丙酮(简称TTA)也能生成在低的
In recent years, due to beryllium in atomic and rocket technology to find new uses, the analysis of beryllium separation has caused great interest. In this paper, the recent ten years on the solvent extraction of beryllium separation methods are reviewed. Chelate system β-diketones: beryllium and β-diketone acetylacetone (abbreviated as AA), benzoylacetone, dibenzoylmethane, 2-gluco-benzoylmethane, Thiophene formyl methane, etc. can form a stable chelate. The production constants of these chelates have been measured by van Uitert et al. In addition beryllium and thiocarboxy trifluoroacetone (TTA) can also be generated at low
