Abstract:V diplomskem delu je bila narejena primerjava med celuloznimi materiali iz treh različnih virov, t. j. bombaža, lesa in bakterij glede na fizikalno-kemijske in morfološke lastnosti. Cilj raziskave je bil ugotoviti, kako izvor in način priprave materiala na osnovi celuloze vplivata na določene lastnosti, zlasti na sposobnost absorpcije barvil. Zastavljena hipoteza je predvidevala značilne razlike med vzorci glede na vir in pripravo. Za karakterizacijo materiala je bilo uporabljenih več metod, t.j. FTIR, SEM, optična mikroskopija, UV-VIS, gravimetrija, in goniometrija. Na podlagi rezultatov je bilo ugotovljeno, da vir in način priprave celuloze izrazito vpliva na morfološko strukturo, hidrofilnost in zmožnost adsorpcije barvila, pri čem je bilo potrjeno, da material iz bombažne celuloze je najbolj učinkovit in ima najvišjo kapaciteto adsorpcije barvila.

Title:Physico-Chemical and morphological comparison of cellulose from different sources
Abstract:In the thesis, a comparison was made between cellulosic materials from three different sources, i.e. cotton, wood and bacteria, in terms of physicochemical and morphological properties. The aim of the study was to determine how the origin and the method of preparation of the cellulose-based material affect certain properties, in particular the ability to absorb dyes. The hypothesis was that there would be significant differences between the samples in terms of source and preparation. Several methods were used to characterise the material, i.e. FTIR, SEM, optical microscopy, UV-VIS, gravimetry, and goniometry. Based on the results, it was found that the source and method of preparation of the cellulose has a marked effect on the morphological structure, hydrophilicity and dye adsorption capacity, and it was confirmed that the cotton cellulose material is the most efficient and has the highest dye adsorption capacity.
