This paper reports results of carbonization of synthetic copolymers 4,4′-diphenyl sulfone dimethacrylate (DPS DM) in the presence of iron salts (Fe(NO 3 ) 3 or FeCl 3 ) as catalysts. The synthesized carbon adsorbents have a spherical shape of grains, a high specific surface area and good sorption and mechanical properties. The structural characteristics were studied using the...
The investigations of preparation of active carbons by carbonization of porous copolymer (4,4′-diphenyl sulfone dimethacrylate) have been described. The carbonization of polymers was carried out in inactive atmosphere (N 2 ) under supervised conditions. A spherical shape of grains is a result of carbonization. The obtained carbon adsorbents were oxidized with nitric acid (6M HNO 3 ...
