Scholarcy highlights

  • A facile and green dual fluorescence sensor was developed for mercury and chemet as an anti-poisoning drug for heavy metal ions
  • The synthesis of carbon quantum dots was performed with a rapid one pot process and the prepared CQDs exhibited a blue luminescence with a 5% quantum yield
  • The off fluorescent is observed in the presence of different concentrations of mercury that is recovered with the addition of chemet
  • Two linear calibrations were validated in the range of 5–500 ng mL−1 and 2.5–22.5 ng mL−1 for Hg and chemet, respectively
  • This methodology was applied to successful measurements of Hg and chemet in the water and human serum samples, respectively
