Caffeine is commonly used in pharmaceutical and personal care products, where it serves both therapeutic cosmetic purposes. However, its widespread presence wastewater from the industries has raised concerns about environmental contamination. This study explores use of a polyaniline (PANI)/cuttlefish bone (CB) nanocomposite as an effective adsorbent for removal caffeine aqueous solutions. The was synthesized by incorporating (PANI) onto cuttlefish flakes, resulting material with hybrid morphology consisting layered nanosheets flaky structures. Adsorption experiments were conducted to determine optimal conditions removal, results showing best adsorption efficiency at pH 7 dosage 0.1 g/L nanocomposite, achieving 80.73% efficiency. maximum capacity 108.33 mg/g—significantly higher than pure CB (55.05 mg/g) PANI (57.71 mg/g). process followed pseudo-second-order kinetic model Langmuir isotherm, indicating chemisorption mechanism monolayer adsorption. Additionally, demonstrated excellent reuse capacity, maintaining over 85% initial after multiple adsorption–desorption cycles, highlighting potential sustainable long-term use. work demonstrates using waste-derived materials like support development low-cost, adsorbents pollutant remediation wastewater. Future studies will explore adsorbent’s applicability other contaminants antimicrobial properties.
