Green synthesis of a magnetite/graphitic carbon nitride 2D nanocomposite for efficient Hg²⁺ remediation

Abstract

Novel nanoadsorbents demonstrate the potential to efficiently eliminate harmful substances, such as Hg2+, from the environment while preserving ecological balance. However, the search for environmentally-friendly nanomaterials as ideal adsorbents, as...

Ultra-Efficient Removal of Mercury from Contaminated Water using Selected Phenylimidazole Derivatives

“…To test the mercury binding potential, these phenylimidazole derivatives were suspended in Milli-Q water (Type I water; Merck, Darmstadt, Germany) at the concentrations of 1 mg g −1 and 10 mg g −1 . These concentrations were chosen to be the same or lower as used in previous work on Hg binding to graphitic carbon nitride material (Chouhan et al, 2019(Chouhan et al, , 2023. Mercury standard solution, obtained by the appropriate dilution of the certified reference material SRM NIST 3133 in Milli-Q water, was then added to a final mercury concentration of 851 ng kg −1 .…”

“…The exceptional mercury binding of compound 3 is presumed to be due to the formation of a stable Hg complex, similar to the one with dithizone, in which two ligands form an N,S-chelate ring with the metal atom (Paci et al, 2000). The possible application of the compound 3 for mercury remediation in contaminated waters also arises from the very short reaction time and even lower required mass, as compared to graphitic carbon nitride (60 min; 40 mg mL −1 ), for example (Chouhan et al, 2023).…”
