The use of waste poly(ethylene terephthalate) and phenol-formaldehyde
resin for the preparation of activated carbons
Polimery 2012, No 9, 635
The results of studies investigating the use of waste poly(ethylene terephthalate) or phenol-formaldehyde resin in a composition with coal-tar pitch for the preparation of activated carbons have been presented. Polymer-pitch compositions containing 10—50 wt. % waste polymer were prepared and their selected physicochemical properties determined. The compositions were carbonized and activated with steam or potassium hydroxide. For the as-prepared activated carbons the iodine adsorption value (LJ), methylene number (LM), specific surface (SBET) and mechanical properties were determined. The obtained activated carbons were also tested for applicability in selected adsorption processes, such as industrial wastewater treatment.
