The aim of this study was to develop powdered and
granular activated
carbonchengde
wanyang activated carbon factorymodified with N
doped TiO2, namely PAC-TiO2N and respective, GAC-TiO2N by
sol-gel method, starting from commercial activated
carbon, for the removal from water of diclofenac (DCF),
an emerging pollutant. The synthesized materials were
characterized systematically and morphostructural, light
absorption and electrical charge properties were
determined. The sorption and photocatalytic capacities of
both materials were determined by batch experiments based
on the kinetic models and the effect of operational
parameters. GAC-TiO2N was selected for further testing in
fixed bed-column experiments envisaging its potential
integration with real drinking water treatment
technology. The GAC-TiO2N tested in UV irradiation-
assisted fixed bed-column filtration for DCF removal
exhibited a great potential for practical application, by
testing in simulated coexisting DCF and humic acids (HAs)
and real surface water spiked with DCF (Bega River,
Timisoara city, Romania). About 80% removal efficiency
was noticed for both DCF and HAs and about 70% of the
organic matter was removed (expressed as total organic
carbon- TOC indicator).

irradiation during filtration allowed the activation of
the GAC-TiO2N filtration layer without TiO2 loss, which
led to longer life-times due to the potential “self-
cleaning” effect and its good stability.
