Abstract
Čestice mikroplastike su čestice veličine manje od pet milimetara te predstavljaju jednog od najvećih zagađivača okoliša, naročito morskog. U ovom radu okarakteriziran je sediment Riječkog zaljeva uzorkovan na četiri lokacije duž obale grada Rijeke, od ušća rijeke Rječine do plaže Ploče. Iz sedimenta su izdvojene mikroplastične čestice, koje su razvrstane prema brojnosti, obliku, boji te veličini. Sastav mikroplastičnih analiziran je na FTIR-u (Fourier-transform infrared spectroscopy). Proveden je i eksperiment u svrhu ispitivanja mogućnosti degradacije polimera u reakciji s acetonom, kloroformom, vodenom otopinom KOH te fosfornom kiselinom pri standardnim uvjetima. Navedeni reagensi također su snimani FTIR-om te je usporedbom vibracijskih vrpci određeno je li došlo do promjena koje ukazuju na degradaciju polimera.
Abstract (english)
Microplastic materials include plastic particles smaller than 5 milimeters that represents one of the main pollutants,especially in the marine environment. This thesis provides data of the sediment of Rijeka bay, sampled at 4 locations along the coast of the city of Rijeka, from the mouth of Rječina river to the beach Ploče. Microplastic particles (MP) were separated from the sediment and classified accroding to abundance, shape, color and size. Chemical composition of MP was not determined due to the difficulty of recording tiny particles on FTIR (Fourier-transform infrared spectroscopy). In the second part of the thesis, known types of plastics were treated with 4 reagents-acetone, chloroform, aqueous solution of KOH and phosphoric acid in order to investigate the possibility of polymer degradation in these reagents. Reagents were recorded by FTIR three times at different time intervals. By comparing the vibration bands of the reagents before and after the treatment of the polymer, it was determined that there were no changes, ie no degradation of the treated polymers.
