Abstract: Studies aimed at comparison of sorption effectiveness
of selected adsorbates from vapor and liquid phases
were carried out on fresh and spent granular active carbon
ROW 0.8 Supra following several years of its exploitation in
a water treatment plant. It was demonstrated that benzene vapor
adsorption was proportional to the available pore volume
of both carbons, while the adsorbed amount of water vapor on
the fresh and spent carbons were similar. This would indicate
that macromolecular humic substances deposited in the pores
of spent granular active carbon were involved in the adsorption
of water. At the same time, it was observed that phenol and
4-chlorophenol adsorption from aqueous solutions was more
than 10-fold lower for the spent carbon than for the fresh one.
Whereas adsorption of trace metal ions (Cu(II), Pb(II)) was
similar for both carbon types. The presented results indicate
that activated carbons following exploitation in water treatment
stations may be still considered as potential sorbents and used
in further applications.
