Abstract

V sklopu magistrskega dela smo izvedli nevtralno, alkalno in kislinsko hidrolizo (depolimerizacijo, kemijsko recikliranje) realnih vzorcev odpadnega poliamidnega tekstila pri različnih reakcijskih pogojih. Zaradi neraziskanosti postopkov ločitve produktov po alkalni in kislinski hidrolizi poliamidnih materialov smo s pomočjo premišljenih preizkusov opravili študijo ločitve produktov, ki je nakazala nekaj smernic za rešitev problema. Alkalna in kislinska hidroliza sta omogočili boljšo depolimerizacijo kot nevtralna hidroliza, zaradi česar bi lahko bili ob dodelanem sistemu ločitve nastalih produktov zelo uporabni v praksi pri recikliranju poliamidnih tekstilnih odpadkov.

Secondary title: Hydrolytic depolymerization as a recycling process for polyamide textile waste - analysis of decomposition products
Secondary abstract: As part of this master’s thesis, neutral, alkaline, and acid hydrolyses (depolymerization, chemical recycling) of real polyamide textile waste samples under different reaction conditions were performed. Because the separation of decomposition products after alkaline and acid hydrolysis of polyamide materials had previously barely been researched, the study of the separation of decomposition products was deliberately organized with many different tests in order to indicate some guidelines for solving the ultimate problem of separation. Alkaline and acid hydrolyses enabled better depolymerization than neutral hydrolysis; therefore, if there were a sufficiently effective separation system, both could be very applicable to the practical use of recycling in the waste management of polyamide textile waste.
