With the growing use of personal care products like sunscreens, chemical pollutants such as UV blockers are increasingly found in aquatic environments. Compounds like THB (2,3,4-trihydroxybenzophenone) and DHMB (2,2′-dihydroxy-4-methoxybenzophenone),), commonly used in sunscreens, have been detected in water, raising environmental concerns. This project aims to develop an eco-friendly method for their removal using alginate beads modified with a deep eutectic solvent (DES) as adsorbents. The alginate-DES composite material was synthesized and characterized for its ability to adsorb THB and DHMB. Adsorption efficiency was evaluated through UV-Vis spectroscopy, optimizing parameters like pH, salinity, and adsorbent dosage. The results showed that the alginate-DES composite effectively removed UV blockers, demonstrating its potential as a green, sustainable solution for water treatment and the removal of chemical pollutants.
