20.500.12556/RUL-173147 Razbarvanje azo barvila reaktivno rdeče 120 s kombinacijo hidrodinamične kavitacije in ne-termične plazme Decolorization of the azo dye reactive red 120 using a combination of hydrodynamic cavitation and non-thermal plasma Neprimerno ravnanje z odpadno vodo v tekstilni industriji predstavlja resen okoljski problem. Odpadna voda, onesnažena z barvili, škoduje okolju, ogroža zdravje ljudi in onesnažuje vodne ekosisteme ter vire pitne vode. Pri iskanju novih tehnologij za čiščenje odpadnih voda kažeta potencial tako hidrodinamična kavitacija, kot tudi ne-termična plazma. Z združitvijo obeh tehnologij se pričakuje sinergistične učinke, in zaradi tega je to predmet intenzivnih raziskav v zadnjem času. Magistrska naloga zajema optimizacijo obratovalnih pogojev naprave, ki združuje obe tehnologiji (hidrodinamično kavitacijo in plazmo) z namenom izboljšanja razgradnje organskih onesnaževal. Za modelno organsko spojino smo izbrali azo barvilo reaktivno rdeče 120. V prvem koraku smo izvedli eksperimente za izris umeritvenih krivulj za določitev koncentracij vodikovega peroksida in barvila reaktivno rdeče 120. Nadalje smo raziskali tvorbo vodikovega peroksida med obratovanjem naprave v vodovodni in destilirani vodi ter primerjali stopnjo razbarvanja barvila v destilirani vodi ob različnih obratovalnih pogojih in izbranih koncentracijah barvila reaktivno rdeče 120. Ugotovili smo, da lahko s spreminjanjem obratovalnih pogojev naprave vplivamo na stopnjo razbarvanja barvila. Improper management of wastewater in the textile industry poses a serious environmental issue. Wastewater contaminated with dyes is harmful to the environment, threatens human health, and pollutes aquatic ecosystems as well as drinking water sources. In the search for new wastewater treatment technologies, both hydrodynamic cavitation and non-thermal plasma have shown considerable potential. Combining these two technologies is expected to generate synergistic effects, which is why this approach has become the subject of intensive research in recent years. This master’s thesis focuses on the optimization of operating conditions in a device that integrates both technologies (hydrodynamic cavitation and plasma) with the aim of improving the degradation of organic pollutants. As a model organic compound, the azo dye Reactive Red 120 was selected. In the first stage, calibration curves were established to determine the concentrations of hydrogen peroxide and Reactive Red 120. Subsequently, the formation of hydrogen peroxide during device operation in tap and distilled water was investigated, and the decolourization efficiency of Reactive Red 120 in distilled water under different operating conditions and dye concentrations was compared. The results show that adjusting the operating parameters of the device can influence the degree of dye decolorization. hidrodinamična kavitacija vodikov peroksid barvilo reaktivno rdeče 120 kavitacijsko-plazemska naprava hidroksilni radikali plazma hydrodynamic cavitation hydrogen peroxide reactive red 120 dye cavitation-plasma device hydroxyl radicals plasma true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-09-13 08:31:02 2025-09-13 08:31:04 2025-11-05 03:34:24 0000-00-00 00:00:00 2025 0 0 XXII, 55 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 532.528:66.099.72:667.281(043.2) 276320 250060291 43946.pdf 43946.pdf 1 5A304CC55B02D5DB4FBA8F74BB5A56A3 de3dbb9ed275d89855a26ddbd3e7bf96c476058f5a8539ae695d28ff8c04d95b 0efc6b85-906b-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=217318 Fakulteta za strojništvo 0 0 0
