Synthesis of Nano Porous Carbon derived from Vinasses Wastes for Crystal Violet Adsorption Application

Abstract An approach to removing crystal violet (CV) dye from aqueous solutions was investigated by nano porous carbon (NC) derived vinasse waste. The NC prepared via pyrolysis carbonization and potassium hydroxide chemical activation process. characterized TGA, FTIR, BET analysis. optimal condition of the used adsorb CV in at room temperature. Different initial concentrations contact times were find effect these parameters. found efficient can be as a feasible alternative for solutions. synthesized temperature 900 °C 1:1 precursor - activator (KOH) ratio provided pore size 3.285 nm maximum surface area 1,018 m 2 /g, which an adsorption. Crystal highly adsorbed within 5 minutes then equilibrium 30 time. amount ion onto adsorbent 3.3, 7.2, 11.2, 19.1 mg/g, respectively.
