Abstract
U ovom diplomskom radu cilj je ispitati učinkovitost ultrafiltracijskih (UF) membrana u uklanjanju Magic Blue bojila i onečišćivala iz modelnih otopina. Promatran je utjecaj granične molekulske mase (engl. Molecular weight cut-off, MWCO), utjecaj matrice te utjecaj koncentracije bojila u otopinama. Korištene su četiri UF membrane u obliku ravnih plahta, a to su: 2, 3, 5 i 10 kDa membrane te tri tekstilne modelne otopine: otopina bojila u demineraliziranoj vodi, modelna otopina i modelne vodovodne otopine. Analizom uzoraka dobiveni su rezultati za sljedeće parametre: mutnoću, kemijsku potrošnju kisika (KPK), električnu provodnost (κ) i intenzitet obojenja. Uz te parametre, praćen je protok tijekom obrada otopina. Ispitane UF membrane pokazale su visoku učinkovitost u uklanjanju mutnoće i intenziteta obojenja (većinom > 90,0 %), a ovisno o prethodno nabrojanim utjecajima učinkovitost se mijenjala za κ (13,0 % - 90,0 %) i KPK (41,7 % - 97,8 %). Protoci su najstabilniji bili kod 2 i 3 kDa membrane, a upravo su te membrane pokazivale najbolje rezultate u uklanjanju bojila i onečišćivala iz otopina.
Abstract (english)
In this master thesis, the aim is to examine the efficiency of ultrafiltration (UF) membranes in removing Magic Blue dyes and contaminants from textile model solutions. The influence of the molecular weight cut-off (MWCO), the influence of the matrix of solutions and the influence of the concentration of dyes in solutions were observed. Four UF membranes in the form of flat sheets were used, namely: 2, 3, 5 and 10 kDa membranes and three textile model solutions: dye solution in demineralized water, model solution and model freshwater solution. The analysis of the samples gives results for the following parameters: turbidity, chemical oxygen demand (COD), electrical conductivity (κ) and color intensity. In addition to these parameters, the flow during treatment was monitored. The examined UF membranes showed high efficiency in removing turbidity and color intensity (mostly > 90,0 %), and depending on the previously mentioned influences, the efficiency changed by κ (13,0 % - 90,0 %) and COD (41,7 % - 97,8 %). The flows were most stable for the 2 and 3 kDa membranes, which showed the best results in removing dyes and contaminants from solutions.
