Abstract

Zadaća ovog diplomskog rada je procjena potencijalnog otpuštanja čvrstih čestica s PES standardnih tekstilnih materijala u procesu pranja, uz promjene sastava kupelji i broja ciklusa pranja. Separacija čestica provedena je membranskom filtracijom, a fizikalno kemijski parametri (pH, elektrovodljivost, mutnoća, ukupna čvrsta tvar-TS, ukupna suspendirana tvar- TSS i ukupna otopljena tvar-TDS) određeni su za efluent od pranja i filtrat. Rezultati ukazuju da je značajniji utjecaj sastava kupelji za pranje nego broj ciklusa pranja na sadržaj čvrste tvari te predstavljaju doprinos razumijevanju problematike mikroplastike, porijeklom od sintetskih tekstilija, u prirodnim recipijentima.

Abstract (english)

The aim of this work is to assess the potential release of solid particles from PES standard textile materials in the washing process, with changes in the composition of the bath and the number of washing cycles. Particle separation was performed by membrane filtration, and physicochemical parameters (pH, electrical conductivity, turbidity, total solids-TS, total suspended matter-TSS, and total solute-TDS) were determined for the washing effluent and filtrate. Results indicate a significant influence of the composition of the bath but no the number of washing cycles on the content of solids and represent a contribution to the understanding of the microplastics particles content, originating from synthetic textiles, in natural recipients.
