Phenolic compounds, which are extensively present in industrial effluents and wastewater, pose significant environmental threats due to their toxicity and severely threaten aquatic ecosystems and human health. In this study, a novel approach employing deep eutectic solvents (DES) based adsorbents was developed to effectively remove phenolic compounds from water. Tetra n octylammonium bromide-Linoleic based adsorbent was synthesized using eco-friendly and biodegradable components, their composition was optimized to enhance the extraction efficiency. Extraction efficiency was compared using a series of DES formulations, the adsorbent was synthesized based on DES to Ethyl Acrylate Ratio and UV cured for further analysis. The DES-based adsorbents demonstrated an extraordinary affinity for phenolic substances. The adsorption process was thoroughly investigated, taking into account DES concentration, reaction time, stir speed, and temperature factors. The results demonstrated high adsorption capacity making them promising candidates for toxic phenolic compound removal. Additionally, the synthesized DES formulations were characterized for their reusability, emphasizing their sustainable nature. This study provides valuable insights into the application of DES-based adsorbents as environmentally friendly and efficient sorbents for phenolic compound removal, contributing to the advancement of green technologies in water treatment.
