Abstract
The aim of this work is the preparation and characterization of activated carbon from synthetic resins based on formaldehyde (phenol-formaldehyde, melamine-formaldehyde, and urea-formaldehyde) activation using potassium carbonate. Obtained by pyrolysis of carbonaceous materials have been evaluated by the sorption technique, TG-analysis, infrared spectrometry and the determination of basic groups using acid-base titration. The influence of preparation conditions on properties of the sorbent have been investigated.
