20.500.12556/RUL-186213 Karakterizacija in ocena izluževanja iz nosilcev biomase v demineralizirani vodi Characterization and Assessment of Leaching of Biomass Carriers in Demineralized Water V diplomski nalogi uporabljeni nosilci so izdelani s 3D-tiskalnikom iz fotopolimerne smole Fun To Do Nano Clear. Smola omogoča visoko natačnost tiskanja, izdelki se malo krčijo in imajo dobro mehansko trdnost, kar je ključno za uporabo v vodnem okolju. Eksperimentalni del bo potekal v dveh sklopih. V prvem sklopu bomo pripravili izlužke nosilcev v demineralizirani vodi ter ugotavljali ali so se iz nosilcev izlužile snovi, pri čemer bomo spremljali koncentracijo raztopljenega organskega ogljika (TOC) in spremembe pH izlužkov v odvisnosti od časa izpostavljenosti. V drugem sklopu bomo izvedli teste strupenosti z malo vodno lečo (Lemna minor), kjer bomo določili vpliv izlužkov na rast in morebitne morfološke spremembe. Cilj je ugotoviti, ali in v kolikšni meri prihaja do izluževanja iz nosilcev ter ali so sproščene snovi potencialno škodljive za vodne organizme. The carriers used in this thesis were produced using a 3D printer with Fun To Do Nano Clear photopolymer resin. The resin enables high printing accuracy, the printed objects shrink very little and have good mechanical strength, which is crucial for use in an aquatic environment. The experimental part will be conducted in two phases. In the first part of the experiment, we will prepare leachates from the carriers in demineralized water and determine whether any substances have leached out of the carriers, while monitoring the concentration of total organic carbon (TOC) and changes in the pH of the leachates as a function of exposure time. In the second set of experiments, we will conduct toxicity tests using duckweed (Lemna minor), in which we will determine the effect of leachates on growth and any morphological changes. The goal is to determine whether and to what extent leaching occurs from the substrates and whether the released substances are potentially harmful to aquatic organisms. izluževanje MBBR nosilci onesnaženje strupenost leaching MBBR carriers pollution toxicity true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-08-28 10:30:25 2026-08-28 10:30:30 2026-09-15 12:17:01 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 26109 291141891 Malesevic_Ana_-_Karakterizacija_in_ocena_izluzevanja_iz_nosilcev_biomase_v_demineralizirani_vodi.pdf Malesevic_Ana_-_Karakterizacija_in_ocena_izluzevanja_iz_nosilcev_biomase_v_demineralizirani_vodi.pdf 1 0DEFE39BABDCCE9630330149FA2708E9 d2497831f13293107dc17343f4223e6c04f7e522c9803b298c43d93c8a7e061b 4f33b04d-a2ba-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245329 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
