W niniejszej pracy zastosowano metody fotokatalityczne do usuwania Tritonu X-100 i płynu do mycia naczyń ze ścieków. Jako fotokataliza ta użyto TiO2 naniesionego na Al2O3. Fotokatalizatory były modyfikowane dodatkiem Cu lub Zn za pomocą metod Klasycznej i Podwójnej Impregnacji. Materiały fotokatalityczne poddano charakterystyce fizykochemicznej za pomocą adsorpcji-desorpcji N2, XRF, XRD, SEM-EDX, spektroskopii Ramana i UV-Vis. Wszystkie katalizatory wykazały się skutecznością w usuwaniu badanych surfaktantów. Dodatek H2O2 (0.01obj.%) nie spowodował polepszenia skuteczności oczyszczania. Najlepsze wyniki uzyskano w czasie pierwszych dwóch godzin oczyszczania.

Photocatalytic methods were applied to remove Triton X-100 and wash-up liquid from wastewater. For the studies Al2O3 supported TiO2 photocatalysts were used. They were modified with Cu or Zn using Classical or Double Impregnation Method. Photocatalytic materials were characterised by N2 adsorption-desorption, XRF, XRD, SEM-EDX, Raman and UV-Vis spectroscopy. All the catalysts were efficient in the removal of surfactants. The addition of H2O2 (0.01vol.%) does not deepen the removal of studied pollutants. The best results were obtained during first two hours of treatment.
