摘要/Abstract

摘要： 利用咪唑桥联的二联吡啶配体与二价金属铁形成双核三股笼状螺旋化合物实现水相环境中选择性捕获并结晶提取四氟硼酸根离子.采用重量法分析了其对四氟硼酸根离子的提取率,提取率可达82wt;以上.

关键词: 金属辅助受体;阴离子提取;选择性结晶;四氟硼酸根离子

Abstract: Tetrafluoroborate (BF4-) ions were selectively captured and crystallized by a diiron (Ⅱ) bis (bipyridyl)-imidazolium triple-stranded complex with a central cavity from an aqueous solution containing other competitive anions.The extracted yield higher than 82wt; was evaluated by gravimetric method.
