Antibiotics are emerging environmental contaminants posing critical health risks due to their tendency to concentrate in living things and eventually infiltrate the human body. Sulfamethoxazole (SMZ) is among the commonly detected antibiotics in wastewater requiring effective removal approach. A sustainable, thermally stable and easily separable magnetic sporopollenin-cellulose triacetate (Msp-CTA) was developed via a simple step synthesis for eliminating SMZ from aqueous solution. The assessment of Msp-CTA characteristics via instrumentations revealed a mesoporous adsorbent having COO-, -OH, CO, and Fe - O as its potential adsorption binding sites. Improved stability gained from blending sporopollenin (Sp) and cellulose triacetate (CTA) was affirmed through TGA analysis. Minimal competition for the adsorption sites by H
