▎ 摘　　要

A novel solid fluorescent sensor with millimeter size, based on graphene quantum dots/polystyrenic anion-exchange resin (GQDs/PS-AER) was obtained for the detection of Fe3+. The linear response range of Fe3+ was obtained from 1 M to 7 M and the detection limit was as low as 0.65 mu M. In addition, the sensor could be regenerated by adding complexing agent EDTA and be separated by using simple filtration. (C) 2016 Elsevier B.V. All rights reserved.
