Colorimetric determination of Hg(II) sensor based on magnetic nanocomposite (Fe3O4@ZIF-67) acting as peroxidase mimics

[Display omitted] •The magnetic nanocomposite (Fe3O4@ZIF-67) possesses excellent peroxidase mimic activity.•The magnetic nanocomposite is good catalytic activity in presence of H2O2.•Colorimetric sensor is highly sensitive and selective detection of Hg2+ ions.•The proposed sensing strategy is succes...
