Highly selective, rapid and sensitive fluorescent test paper based on graphene quantum dots for on-line detection of metal ion

Abstract

In this work, the test paper based on N-doped graphene quantum dots and graphene quantum dots were designed and prepared. They exhibited a highly selective fluorescence quenching response to Hg(II) and Fe(III) in water for 3.0s~2.0 min, respectively. Furthermore, the low detection limit (0.1 μM) of the test paper was obtained, which was lower than the toxic level of Hg(II) and Fe(III). Moreover, the concentration of metal ion in water was directly determined according to the quenching time of fluorescent test paper by naked eyes. Therefore, a convenient paper sensor for rapid, sensitive and selective detection of metal ions in water was developed, which was expected to apply in accurate detection and large-scale monitoring of heavy metal pollution in the environment.
