Abstract:Sodobna potrošniška družba ima kot posledico proizvodnjo velike količine najrazličnejših materialnih dobrin in hkrati velike količine odpadkov. Mednje sodijo tudi odpadni poliestrni tekstilni materiali. Slednji so biološko težko razgradljivi, zato je ustrezno ravnanje z njimi še toliko bolj pomembno. Kot učinkoviti kemijski postopki razgradnje so se izkazale različne oblike hidrolize. Diplomsko delo smo zato namenili analizi odpadnih poliestrnih tekstilnih materialov z alkalno in nevtralno hidrolizo z uporabo potenciometričnih titracij v nevodnem mediju. Uporabljeni sta bili topili dimetil sulfoksid (DMSO) in benzil alkohol. Na podlagi meritev in izračunov končnih karboksilnih (COOH) skupin smo prišli do ugotovitve, da je učinkovitost razgradnje odvisna od kombinacije več dejavnikov, med katerimi so poleg vrste hidrolize še sestava tekstilnega materiala, njegova predpriprava ter reakcijski čas razgradnje.

Title:Determination of functional end groups of hydrolysis products of waste polyester textile materials
Abstract:Consequence of modern consumer society is production of large amounts of material goods and waste. The latter include waste polyester textile materials, which are poorly biodegradable, therefore proper management of them is even more important. Different forms of hydrolysis have been proven as effective chemical degradation processes. Diploma work presented analysis of textile waste polyester degradation products after alkaline and neutral hydrolysis, using potentiometric titrations in a non-aqueous medium. Dimethyl sulfoxide (DMSO) and benzyl alcohol were used as solvents. Based on the measurements and calculations of the carboxyl end groups analysis, we concluded, that decomposition efficiency depends on a combination of several factors, among which are, in addition to the type of hydrolysis, a composition of textile material, its pre-treatment and the reaction time of degradation.
Keywords:polyester, waste textile, alkaline hydrolysis, neutral hydrolysis, titrations
