Modeling and Regeneration Studies for the Removal of Crystal Violet Using Balanites aegyptiaca Seed Shell Activated Carbon

Activated carbon (ACBS) derived from Balanites aegyptiaca seed shell was employed to remove crystal violet (CV) aqueous medium. The characterization of this ACBS has been conducted using analytical techniques such as SEM and EDS. adsorption parameters investigated were: contact time (5-120 min), temperature (303-333 K) initial concentration (100-500 mg/l). data were interpreted by kinetic, isotherms thermodynamic equations. kinetic match the pseudo-second-order model well, both external diffusion internal influenced dye onto adsorbent. isotherm is in concurrence with Freundlich intimating multilayer coverage CV on heterogeneous surface ACBS. quantities like ?S°, ?H° ?G° computed Gibbs plot. results implicated practicability endothermicity process. Regeneration studies show effectiveness CH3COOH solution recovery than distilled water, H2SO4, HCl, HNO3, NaOH solutions. regenerated recycled five times sustained an efficiency 92.08%.
