Projekt ten koncentruje się na skutecznym i przyjaznym dla środowiska usuwaniu sześciowartościowego chromu (Cr(VI)) i barwnika Rose Bengal z roztwor�w wodnych przy użyciu hydrofobowych rozpuszczalnik�w glęboko eutektycznych (DES). Ścieki przemyslowe zawierające metale ciężkie i barwniki syntetyczne stanowią poważne zagrożenie dla środowiska i zdrowia ze względu na ich toksycznośc, trwalośc i bioakumulację. Aby rozwiązac te problemy, opracowano zielony system rozpuszczalnik�w wykorzystujący chlorek tetra metyloamoniowy (HBA) i kwas oktanowy (HBD), tworząc stabilny hydrofobowy DES.Przygotowany DES scharakteryzowano za pomocą gęstości, pH, FTIR, spektroskopii UV-Visible i analizy DSC, aby zrozumiec jego wlaściwości fizykochemiczne. Eksperymenty ekstrakcji rozpuszczalnikiem przeprowadzono w r�żnych warunkach pH, temperatury, czasu kontaktu i początkowego stężenia zanieczyszczeń. Spektroskopia UV-Vis zostala wykorzystana do skonstruowania krzywych kalibracyjnych i ilościowego określenia wydajności ekstrakcji. Og�lnie rzecz biorąc, badanie wykazalo, że hydrofobowe DES są oplacalnymi, biodegradowalnymi i wysoce wydajnymi zielonymi rozpuszczalnikami, oferującymi zr�wnoważoną alternatywę dla konwencjonalnych rozpuszczalnik�w organicznych do oczyszczania ściek�w i usuwania zanieczyszczeń.
