Selective Extraction of Tetrafluoroborate via Crystallizing by a Triple-Stranded Fe2 L3 Receptor from an Aqueous Solution

Abstract

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.
