Determination of thiomersal and mercurial residues by photo-degradation and flow injection analysis with luminescence probing using carbon quantum dots prepared from thiourea
(Elsevier BVNetherlands, 2023)Thiomersal is an organomercurial compound but, despite that, it is widely used in vaccines formulations to inactivate organisms and toxins and to prevent microbial growth during storage and use. In this work, thiomersal ... -
Evidence of mercury sequestration by carbon nanotubes and nanominerals present in agricultural soils from a coal fired power plant exhaust
(Journal of Hazardous Materials, 2019-10-15)Mercury (Hg) in agricultural soils could have negative effects on the environment and the human health. The exposure to high level of Hg through different absorption pathways, such as ingestion and diet through soil-plant ... -
Modeling the adsorption of divalent metallic cations onto multi-walled carbon nanotubes functionalized with COOH
(ElsevierNetherlands, 2022-11)In this work, the adsorption of Cd2+, Pb2+, and Hg2+ ions onto multi-walled carbon nanotubes (MWCNTs) functionalized with COOH is investigated as a function of temperature (298–328 K). For all the investigated ions, ... -
