Bentonite-ionic liquid composites for Congo red removal from aqueous solutions

Ruta Ozola-Davidane et al.

Summary: The research aims to prepare an environmentally friendly new class of clay sorbents modified with ionic liquids for potential applications in wastewater treatment from the textile industry. Imidazolium-based ionic liquids with different alkyl chain lengths were successfully intercalated in sodium bentonite via an ion exchange reaction, enhancing the clay's sorption capacity for Congo red dye. The modified clays, especially those modified with 1-dodecyl-3-methylimidazolium chloride, showed much higher Congo red sorption capacity compared to unmodified bentonite.
