Sorption Reaction of Chromium(VI) Ions with Carbon Adsorbents

The sorption interaction of chromium(VI) ions with carbon adsorbents was studied by the physicochemical methods of energy dispersive X-ray spectroscopy, IR spectroscopy, and modeling using the Firefly801 program. A probable sorption mechanism is proposed, which can be considered as the sum of proces...

Description
Summary:The sorption interaction of chromium(VI) ions with carbon adsorbents was studied by the physicochemical methods of energy dispersive X-ray spectroscopy, IR spectroscopy, and modeling using the Firefly801 program. A probable sorption mechanism is proposed, which can be considered as the sum of processes determined by external and internal diffusion of ions, electrostatic interaction, and ion exchange reactions.
