Abstract

Adsorption of p-nitrophenol from aqueous solution by combined membrane-adsorption technology was studied. Activated carbon samples were synthesized on the base of industrial by products (coal tar pitch) and biomass. Synthetic activated carbon synthesized from mixture of coal tar pitch and furfural by thermo-oxidation treatment with sulfuric acid at 200oC, and subsequent carbonization in nitrogen atmosphere at 600 oC, followed by hydro-carbonyzation at 800oC. Biomass based activated carbon was obtained by hydro-carbonization of apricot stones at 800oC. Copolymer solutions were prepared by copolymer dissolution in DMSO. Activated carbon powder is added and the solutions were homogenized. The suspensions are cast on a glass and immersed in isopropyl alcohol - water mixture to form membranes. Five different membranes were synthesized from copolymer (acrylonitrile-vinyl acetate), and two types of activated carbon (synthetic and biomass based) in different amounts were added. It was established that the removal of p-nitrophenol varies from 9.2 to 29.73 % depending on the type of membranes. Additional removal of the pollutant remaining in water was achieved after subsequent adsorption with synthetic activated carbon, which allows us to achieve up to 98.9 % pollutant removal.
