Optimized arsenic, selenium and mercury determinations in aqueous solutions by energy dispersive x-ray fluorescence after preconcentration onto zirconium-loaded activated charcoal

Adsorption onto zirconium-loaded activated charcoal (ZrC ∗) allows the efficient collection of arsenic, selenium and mercury from aqueous solutions in a thin layer, and at the same time removes or minimizes elemental interferences. When this preconcentration method is combined with energy dispersive...
