| Abstract: | We have carried out an assessment of the content of aromatic compounds (o-nitrophenol, o-aminobenzoic acid) in grains of activated carbon of a biofilter at the stage of stationary water treatment. It was found
that the removal degree of aromatic compounds by the biofilm of biologically activated carbon in great measure is determined
by the value of the decreasing of Gibbs free energy of adsorption (−ΔG
a
). It is shown that due to the competing action of the biofilm part of the accessible surface of activated carbon is not used
for adsorption of organic matter. |
