【 摘 要 】

A novel nanofibrous film chemosensor was designed and fabricated for detecting Fe3+. It displayed good sensitivity and selectivity as a sensing material for Fe3+. The addition of Fe3+ would induce obvious fluorescent quenching of the nanofibrous film and the other common metal ions did not interfere in the recognition of Fe3+. The detection limit for Fe3+ of this sensing material was calculated to be 10.63 μmol L-1. Moreover, the nanofibrous film could not only be regarded as a chemosensor for detecting Fe3+, but also as an adsorbent to remove Fe3+ with high efficiency in solution. The adsorption capacity was calculated to be 13.93 mg g-1 of Fe3+/nanofibrous film from Langmuir plot.
