20.500.12556/DKUM-63065 OBDELAVA ODPADNIH VOD IZ PROIZVODNJE 5-NOK (5-nitro-8-hidroksikinolin) TREATMENT OF WASTEWATER FROM THE PRODUCTION OF NITROOXINE (5-nitro-8-hydroxyquinoline) V diplomski nalogi smo preučevali možnost čiščenja odpadnih voda, ki nastajajo pri sintezi omenjene farmacevtske učinkovine s pomočjo različnih oksidacijskih metod. Čiščenje odpadne vode iz proizvodnje 5-nitro-8-hidroksikinolin (5-NOK) smo izvedli s H2O2 postopkom, z ozoniranjem (O3) in z kombinacijo H2O2/ O3 ter s Fentonovim reagentom (H2O2/Fe2+). Uspešnost uporabljenih metod čiščenja odpadnih vod smo ovrednotili s pomočjo naslednjih parametrov onesnaženja odpadne vode: kemijske potrebe po kisiku (KPK), 8-hidroksikinolina in 5-nitrokinolina. S Fentonovim reagentom smo pri obdelavi odpadne vode dosegli najvišjo stopnjo znižanja vrednosti KPK obdelanih vod (72 % znižanje). Pri degradaciji 8-hidroksikinolina in 5-nitrokinolina pa smo dosegli popolno degradacijo 5-nitro-8-hidroksikinolina. In the graduation thesis, we examined the treatment possibilities for wastewater generated in the process of synthesis of the said pharmaceutical therapeutic substance, using a variety of oxidation methods. Wastewater from production of 5 nitro-8 hydroxyquinoline (5-NOK) was treated with the H2O2 procedure; with ozone wastewater treatment (O3); with a combination of H2O2/O3; and with the Fenton's reagent (H2O2/Fe2+). The effectiveness of the wastewater treatment methods employed was evaluated using the following wastewater pollution parameters: chemical oxygen demand (COD), 8 hydroxyquinoline, and 5 nitroquinoline. The highest COD decrease in wastewater treatment was attained using the Fenton's reagent (72% decrease in the treated wastewater). With degradation of 8 hydroxyquinoline and 5 nitroquinoline, we attained complete degradation of 5 nitro-8 hydroxyquinoline. 5-nitro-8-hidroksikinolin Fentonov reagent H2O2/O3 KPK 5-nitro-8-hydroxyquinoline Fenton reagent H2O2/ O3 COD true true false [K.
