Analgesic consumption increased significantly during the COVID-19 pandemic. A high concentration of this kind drug is discarded in urine, reaching effluents rivers, lakes, and seas. These medicines have brought serious problems for flora and, especially, ecosystems' fauna. This paper presents results removing diclofenac, ibuprofen, paracetamol an aqueous solution, using Sargassum spp. from Caribbean coast. The study consisted mixing each solution with functionalized spp a container under constant agitation. Therefore, work represents alternative to solve two biggest recent years; first, reduction overpopulation sargassum through its use remediation environment. Second removal waste used excessively Liquid samples were taken at intervals 10 min analyzed by fluorescence determine drug. sorption capacity was 2.46, 2.08, 1.41 μg/g, corresponding 98 %, 84 54 % removal, respectively. three drugs notably favored increasing temperature 30 40 °C, efficiencies close 100 %. Moreover, system maintains effectiveness various pH values. In addition, can be reused up cycles without reducing capacity. wide diversity organic compounds favors biosorption drugs, them kinetic mechanisms. On other hand, X-ray diffraction, FTIR spectroscopy, TGA analysis, scanning electron microscopy before after removal. showed evident modification structure morphology algae demonstrated presence biosorbed drugs. sustainable, simple, economical, environmentally friendly, highly efficient, scalable domestic industrial level that aquatic environments.
