Abstract
Several processes in the pharmaceutical industry require large amounts of water that
inevitably are contaminated. Pharmaceuticals are often not completely removed in
sewage treatment plants and, therefore, are emitted into receiving water systems.
Recently, the use of advanced oxidation processes (AOPs) for complete destruction of
contaminants has been popular. AOPs are based on the production of reactive species
such as hydroxyl radicals that oxidized a wide range of organic pollutants quickly and
non-selectively.AOPs include photocatalytic systems like the combination of
semiconductor and lighting, and oxidants. Photocatalytic process as anenvironmentally
friendly process has considerable advantages over some existing technologies;can be
carried out under ambient conditions (atmospheric oxygen is used as oxidant and solar
light can be used as light source) and usually leads to complete mineralization of
organic pollutants into CO2 and H2O. This study focuses on the removal of the
pharmaceutical Atenolol (ATL) by TiO2photocatalysis. Operating factors such as initial
concentration, photocatalyst dosage, and pH solution were investigated in order to
evaluate the extent of mineralization.
