| 中文摘要 | ionic liquid (il)-based extraction is a promising high-efficiency and environmentally benign separation technology. imidazolium ils lose their cations or anions to aqueous phase during extraction, the release lead to water pollution. to develop sustainable il-based extraction system, we firstly investigate quaternary ammonium nitrate il-based extraction strategy. alkylated phosphine oxides (cyanex925) in tricaprylmethylammonium nitrate ([a336][no(3)]) are studied for separating sc from y and lanthanides. distribution ratio and separation factor of the cyanex925-[a336][no(3)] system for sc(3+) are by far larger than those achieved using cyanex925-[c(8)mim][pf(6)] system. the stability and solvating mechanism of cyanex925-[a336][no(3)] extraction system can avoid release of [a336][no(3)] to aqueous phase. the novel quaternary ammonium nitrate il-based extraction system is an efficient and sustainable separation strategy. published by elsevier b.v. |
