Dieses Projekt befasst sich mit der effizienten und umweltfreundlichen Entfernung von sechswertigem Chrom (Cr(VI)) und dem Farbstoff Rose Bengal aus w�ssrigen L�sungen unter Verwendung hydrophober tief eutektischer L�sungsmittel (DES). Industrielle Abw�sser, die Schwermetalle und synthetische Farbstoffe enthalten, stellen aufgrund ihrer Toxizit�t, Persistenz und Bioakkumulation ernsthafte Umwelt- und Gesundheitsrisiken dar. Um diesen Problemen zu begegnen, wurde ein gr�nes L�sungsmittelsystem entwickelt, das Tetramethylammoniumchlorid (HBA) und Octans�ure (HBD) verwendet und ein stabiles hydrophobes DES bildet.Das hergestellte DES wurde durch Dichte, pH-Wert, FTIR, UV-Visuelle Spektroskopie und DSC-Analyse charakterisiert, um seine physikochemischen Eigenschaften zu verstehen. Experimente zur L�sungsmittelextraktion wurden unter verschiedenen Bedingungen wie pH-Wert, Temperatur, Kontaktzeit und anf�nglicher Schadstoffkonzentration durchgef�hrt. Mit Hilfe der UV-Vis-Spektroskopie wurden Kalibrierungskurven erstellt und die Extraktionseffizienz quantifiziert. Insgesamt zeigt die Studie, dass hydrophobe DESs kosteng�nstige, biologisch abbaubare und hocheffiziente gr�ne L�sungsmittel sind, die eine nachhaltige Alternative zu herk�mmlichen organischen L�sungsmitteln f�r die Abwasserbehandlung und Schadstoffentfernung darstellen.
