Apstrakt
Kontaminacija vodnih resursa otpadom aktivnih farmaceutskih sastojaka je među glavnim problemima životne sredine. Da bi se sprečili veliki poremećaji u prirodnim vodama, treba uspostaviti efikasan i ekološki prihvatljiv postupak uklanjanja zamućenja od strane uobičajenih zagađujućih materija, kao što je paracetamol. U ovoj studiji je istraživana upotreba nekoliko prirodnih dubokih eutektičkih rastvarača u cilju smanjivanja zamućenosti simulirane vode kontaminirane paracetamolom ispod standardne granice zamućenosti koju preporučuju Nacionalni standardi kvaliteta vode u Maleziji (50 NTU). Određeni su optimalni radni parametri (količina eutektičkih rastvarača, vreme mešanja i radna pH vrednost). Pod optimizovanim uslovima, korišćenje eutektičkog rastvarača na bazi stearinske kiseline dovelo je do najvećeg smanjenja zamućenosti od 97,5 %. Visoke performanse koagulacije su ispitivane na osnovu molekularne interakcije, korišćenjem COSMO-RS (CONductor like Screening MOdel for Real Solvents)
s-profila i s-potencijala (histogram raspodele gustine naelektrisanja preko molekularne površine) i pokazali su visok afinitet između eutektičkih rastvarača i paracetamola. Zaključeno je da su eutektički rastvarači obećavajući kandidati za uklanjanje zamućenosti vode izazavane prisustvom paracetamola i prikladni su u daljim istraživanjima tretmana otpadnih voda.
