Abstract

Climate change is impacting the severity of water pollution, and polluted water bodies have an impact on climate change. Increased precipitation and atmospheric temperature changes affect the flow of water bodies, causing interactions in the chemical kinetics of the contaminants present in water that should not be present in the first place. Likewise, anthropogenic activities and their waste management require urgent actions for the mitigation and adaptation to climate change. Fats, oils and grease (FOG) present in water are difficult to remove and affect the drinking water or wastewater treatment trains; that is, FOG can aggregate and clog subsequent operations and are susceptible to temperature changes. Relevant advances in FOG removal using oleic acid as a model compound submitted to a liquid–liquid extraction under menthol:lactic acid deep eutectic solvent (DES) mixture is presented.
