摘要
开发了一种环境友好的水相体系，用于使用聚乙二醇/盐体系从152Eu和60Co中分离108mAg。选择12种盐（9种无机盐，3种有机盐）和PEG 4000形成ATPS，其中3mL 2mol·dm−3的ATPS分离效果最好 K3PO4:3 mL PEG 4000，然后是3 mL 2 mol·dm−3 Na2SO4:3 mL PEG-4000。在这两种情况下，银都优先在富含PEG的相中提取。获得的分离因子为SAg/Co = 2.11 × 103和SAg/Eu = 2.79 × 102在2 mol·dm−3 K3PO4:PEG 4000组合的情况下。
Separation of Long-Lived 108mAg from 152Eu and 60Co Using Polyethylene Glycol Based Aqueous Two Phase Systems
An environmentally benign aqueous two phase system has been developed for the separation of 108mAg from 152Eu and 60Co using polyethylene glycol/salt system. Twelve salts (nine inorganic, three organic) and PEG 4000 were chosen to form the ATPS out of which, the best separation was observed for 3 mL 2 mol·dm−3 K3PO4: 3 mL PEG 4000 followed by 3 mL 2 mol·dm−3 Na2SO4: 3 mL PEG 4000. In both cases, silver was preferentially extracted in the PEG rich phase. The separation factors achieved were SAg/Co = 2.11 × 103 and SAg/Eu = 2.79 × 102 in the case of 2 mol·dm−3 K3PO4: PEG 4000 combination.
期刊介绍：
Journal of Solution Chemistry offers a forum for research on the physical chemistry of liquid solutions in such fields as physical chemistry, chemical physics, molecular biology, statistical mechanics, biochemistry, and biophysics. The emphasis is on papers in which the solvent plays a dominant rather than incidental role. Featured topics include experimental investigations of the dielectric, spectroscopic, thermodynamic, transport, or relaxation properties of both electrolytes and nonelectrolytes in liquid solutions.
