Abstract Smoked cigarette butts are a non-biodegradable pollutant that has damaged the planet. However, carbon materials derived from have proven to be suitable for various applications. We synthesized butt-derived via hydrothermal carbonization and chemical activation methods then converted it an electrode material capacitive deionization. The fabricated material, SCC-750, exhibited relatively high salt adsorption capacity of 10.27 mg g−1. excellent CDI (capacitive deionization) performance is due specific surface area 3,093.10 m2 g−1 pore volume 1.754 cm3 This work offers new method recycle harmful by converting them into promising
