To obtain evidence for difference in the absorptive forms of HgCl2 and HgO from duodenum, the Hg distributions after the duodenal administration of HgCl2 and HgO and the effect of Na2SeO3 on their Hg distributions were compared. The Hg concentrations

Mercury electrodes preconcentrate metal chalcogenide nanoparticles effectively, enabling their detection at submicromolar concentrations (as Sigma chalcogenide) by adsorptive cathodic stripping voltammetry. Understanding the unique behavior of nanoparticle analytes during preconcentration is critical for lowering detection limits and for quantification. A
