A simple chalcone-based fluorescent chemosensor for the detection and removal of Fe3+ ions using a membrane separation method

摘要

A simple chalcone-based fluorescent chemosensor 1, capable of detecting Fe3+ in aqueous media, has been designed and synthesized by the condensation of 3-formyl-2-hydroxyquinoline and acetophenone. The Fe3+ recognition processes are shown to be barely influenced by other coexisting metal ions, and are found to be reversible with EDTA. Moreover, the sensor is applied in the Fe3+ removal process from environmental water samples by using a membrane separation method.
