Abstract
An investigation of the oxidized and modified carbon materials and sorbents around them has been carried out by physicochemical methods (electron microscopy, thermoanalysis, X-ray diffraction, and IR spectroscopy). The processes of mercury sorption to the new modified carbon sorbents under static and dynamic conditions are studied with model solutions and processing media. It has been found that adsorption capacity for mercury depends on oxidation state of the carbon surface and on the properties of the introduced modifier.
