Photocatalytic degradation of Reactive blue 268 dye

Tekstilne odpadne vode vsebujejo različna barvila, ki povzročajo obarvanost le teh. Zato je obarvanost eden izmed parametrov, ki predstavlja okoljski in estetski problem poleg tega pa lahko takšna voda vsebuje toksične snovi. Iz tega vidika človek dandanes posveča veliko pozornosti postopkom za razgradnjo odpadnih obarvanih vod. Diplomsko delo prikazuje fotokatalitično razgradnjo modelne vodne raztopine z onesnaževalom reaktivnega barvila Reactive Blue 268 s pomočjo naprednega oksidacijskega postopka (AOP) UV/H2O2. Ugotovili smo, da je UV/H2O2 sam po sebi uspešen postopek za razgradnjo obarvane modelne vode, ob dodatku katalizatorja MnTACN (Manganov 1,4,7-trimetil-1,4,7-triazociklanon) pa se uspešnost poveča. Test toksičnosti smo izvajali s pomočjo bakterij Vibrio fischeri.Textile waste waters contain different dyes, which causes colouring them. Therefore coloration is one of parameters that represents an environmental and aesthetic problem, besides that, such water can contain toxic substances. From this point of view, people nowadays devote a lot of attention to processes for degradation of coloured waste waters. A degree paper demonstrates photocatalytic degradation of model water solution with pollutant reactive colour Reactive Blue 268, with help of advanced oxidation procedure (AOP) UV/H2O2. The results show that UV/H2O2 by itself is very successful process for degradation of coloured model water. By adding catalyst MnTACN (1,4,7-trimethyl-1,4,7-triazacyclonane) the procedure becomes even more successful. Test of toxicity was made with help of bacteria Vibrio fischeri
