ABSTRACT
Currently, growing attention has been paid to the sensitive determination and removal of Cu2+ because excessive levels of Cu2+ could do harm to organisms. Herein, a novel diethanolamine-modified magnetic fluorescent Fe3O4@ZnS nanoparticle (MFNP) for simultaneous detection and removal of Cu2+ was designed and synthesized through dithiocarbamate linkage strategy. The characterization of MFNP was confirmed by transmission electron microscope (TEM), infrared (IR) and emission spectra. The results showed that MFNP could quantificationally detect Cu2+ with high sensitivity and selectivity under a broad pH range (pH 4.5-9). The removal of Cu2+ was achieved by the aggregation-induced sedimentation (AIS) strategy and by external magnetic field.
