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...

| description | 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 x-ray fluorescence, the resulting analysis is accurate and precise. The method is simple and rapid and almost free from contamination because only a small amount of sodium hydroxide or nitric acid is required for pH adjustment, in addition to ZrC
∗ adsorbent. Spectral interferences from other elements are negligible because the ZrC
∗ adsorbent is highly selective. The procedure is also suitable for the determination of organometallic compounds of arsenic, selenium and mercury. |
