Graphical abstractTwo types of graphene quantum dots (GQDs) with different fluorescence emission wavelength were obtained by treating sulfydryl group (-SH) amino acid glutathione (GSH) in the presence and absence of AgNO3 via one pot route, respectively. These GQDs have special recognition ability for metal ions. The one respond rapidly towards the presence of Fe3+ ions, and can be used as a probe to detect Fe3+ ions in waste water, while the other have a special recognition to Hg2+ ions.
