Magnetically recoverable fluorescence chemosensor for the adsorption and selective detection of Hg2+ in waterElectronic supplementary information (ESI) available. See DOI: 10.1039/c3em00462g
In order to conveniently and effectively detect the heavy metal ion Hg 2+ existing in water, a magnetic fluorescence chemosensor has been strategically prepared by immobilizing a Rhodamine B derivative RhB-tris(2-aminoethyl)amine on Fe 3 O 4 @SiO 2 -Au@PSiO 2 composites via gold particles. The adsor...

gold particles. The adsorption and detection for Hg
2+
ions were investigated with fluorophotometry. This chemosensor shows high sensitivity and high selectivity for Hg
2+
over other metal cations owing to the ring opening of the rhodamine fluorophore selectively induced by Hg

. In addition, the presence of Fe
