A Novel Biochar from Agro-Industrial Waste: Synthesis, Characterization, and Application for Acetylsalicylic Acid Removal.

ABSTRACT: Due to drugs not being completely metabolized and excreted in their original form or as byproducts that contaminate water resources, the conventional treatment process often fails to remove these pollutants. Consequently, some studies seek to use waste to create materials capable of purifying water. Adsorption, being a process of low complexity and operational cost, stands out as a widely used process for wastewater treatment. In this context, the present work aims to synthesize and characterize a novel biochar from Lagenaria siceraria for the removal of the acetylsalicylic acid (ASA) drug by the adsorption process (kinetic, equilibrium, and thermodynamic) and to evaluate its ecotoxicity in Artemia salina. The biochar showed a heterogeneous, porous, and negatively charged sur
