Conversion of polyolefin wax to carbon adsorbents by thermooxidation treatment

Carbon adsorbents with different properties were obtained from furfural and mixture of furfural and polymer waste (polyolefine wax) with different activation reagents and different conditions of treatment. The carbons obtained have insignificant ash content. It was determined, that pore volume, pore size distribution and the chemical character of the surface of the carbon adsorbents depend on the selected activation reagents and temperature of treatment. The IR spectra and Boehm method show that various oxygen-containing groups with acidic (carboxylic, carboxylic in lactonelike bonding, phenolic, hydroxyl and carbonyl groups) and basic character are present on the carbon surface. Our investigations reveal that on the base of polymer waste, different activated carbons were obtained, and they could be used as effective adsorbents for removal of toxic metal and organic pollutants.
