Abstract

Modified nitrogen- and sulfur-containing sorbent were produced on the basis of industrial activated carbons by their thermal treatment with preliminary impregnation with thiourea and ammonium rhodanide. It was found tat the modification affects the porous structure, surface physicochemical properties, and sorption characteristics of carbon sorbents. The increase in the protection duration of thiourea-modified carbons by 67%, compared with the starting carbons, at a relative air humidity of 70% is illustrated.
