聚硫（氧）醚类低聚物对贵金属的萃取性能——Ⅰ.对单个贵金属离子的萃取性能及其影响因素 EXTRACTION PROPERTIES OF POLYTHIOETHERS AND POLYETHERS FOR NOBLE METALS Ⅰ.Extraction properties of oligomer-extractants for single metal ions 徐羽梧 Xu Yuwu Xu Feng 1 first-author 徐锋 1 武汉大学化学系 武汉大学化学系 Department of Chemistry,Wuhan University Department of Chemistry,Wuhan University 研究了一系列以聚硫醚为主链、侧链带不同取代基的低聚物对贵金属离子的萃取和反萃取性能,并与相应的聚氧醚为主链的低聚物进行比较。研究了影响萃取性能的某些因素。 The extraction properties of nine oligomers with polythioether or polyether as their main chains and various functional groups in the side Chains for single metal ions[Ag（Ⅰ）、Au（Ⅲ）、Pd（Ⅱ）、Pt（Ⅳ）]were investigated. An approch was attempted to some effects on extraction such as media acidity,concentration of metal ions,and kind of diluents.The back-extraction can be carried out with ease and the extractants after regeneration can be used repeatedly without the obvious change of their extraction capacities. 聚硫醚 低聚物 贵金属 萃取剂 polythioethers oligomer noble metal extraction and back-extraction O623.82;O632.32 国家自然科学基金资助课题 1992-02-01 2021-04-01 2
