Degradation of Food industrial pollutants by photocatalysis with immobilized titanium dioxide
Original language description
The paper deals with application of advanced oxidation processes in degradation of surfactants, which represent large group of pollutants in food industrial waste waters. The photocatalytic degradation of two surfactants, an anionic sodium dodecyl sulphate (SDS) and cationic N-cetyl-N,N,N-trimethylammonium bromide (CTAB), was tested in a lab-scale UV reactor (Mikropur, Czech Republic) with immobilized titanium dioxide catalyst (P25, Degussa). Various conditions were verified, e.g. initial detergent concentrations (1.2-18.7 mg/l), oxygen flow rates (0 or 72.2 ml/min) and amount of catalyst used. The degradation in a presence of catalyst, oxygen and UV irradiation was the fastest process with maximum achieved rate constants of 0.0503 minMINUS SIGN 1 at anionic surfactant degradation and 0.342 minMINUS SIGN 1 at cationic detergent degradation. The energy demands for SDS degradation were also calculated and possible scale-up into large industrial scale discussed.
