Abstract
U današnje vrijeme novi predmet zanimanja znanstvenika postaju tzv. ''nova zagađivala'' odnosno kontaminanata koji stvaraju zabrinutost (eng. Contaminants of Emerging Concern, CEC) koja su postala veliki problem današnjice. Ovu raznoliku skupinu potencijalno opasnih spojeva čine prirodne ili sintetičke kemikalije ili mikroorganizmi kojima se do sada nije pridavalo značenje kao zagađivalima te sve većim ispuštanjem u okoliš predstavljaju potencijalnu opasnost za ekosustav. Farmaceutici i sredstva za osobnu higijenu predstavljaju jednu od najvažnijih skupina novih zagađivala. Membranski separacijski procesi pokazali su se kao učinkovite metode uklanjanja spomenutih zagađivala iz okoliša. U ovom radu provelo se ispitivanje učinkovitosti uklanjanja odabranih antibiotika (ciprofloksacin i sulfametoksazol) komercijalno dostupnim reverzno osmotskim (RO) te nanofiltracijskim (NF) membranama iz binarnih otopina. Reverzno osmotska membrana bila je XLE, a nanofiltracijske membrane NF i NF90. Najveću učinkovitost separacije pokazala je RO XLE membrana, iako ostale membrane isto pokazuju vrlo visoku učinkovitost. Mehanizam separacije farmaceutika je isključenje veličinom. Provedena je FTIR analiza ispitivanih membrana prije i poslije obrade antibiotika gdje je potvrđeno da nije došlo do interakcija.
Abstract (english)
Nowadays, the ''new pollutants'', i.e., the Contaminants of Emerging Concern (CEC), which have become a major problem, are of great interest to scientists. This diverse group of potentially hazardous compounds consists of natural or synthetic chemicals or microorganisms that until now have not been considered as pollutants, and with increasing release into the environment represent a potential danger to the ecosystem. Pharmaceuticals and personal care products represent one of the most significant groups of new pollutants. Membrane separation processes have proven to be effective methods for removing these from the environment. In this research thesis, the efficacy of removal of the selected antibiotics (ciprofloxacin and sulfamethoxazole) from binary solutions by commercially available reverse osmosis (RO) and nanofiltration (NF) membranes was performed. The reverse osmosis membrane was XLE, the nanofiltration membrane was NF and NF90. The RO XLE membrane showed the highest separation efficiency, although other membranes also showed very high efficiency. The mechanism of pharmaceutical separation is based on size exclusion. FTIR analysis of the tested membranes was performed before and after treatment with antibiotics, confirming that no interactions occurred.
