Abstract
Crystal violet (CV) was removed from aqueous solutions using walnut shell (WS) as an adsorbent. The effect of initial pH, contact time, adsorbent level and temperature on CV adsorption, were studied in batch mode. The results indicated that both the Langmuir and the Freundlich equations effectively described the adsorption equilibrium. A pseudo second-order kinetics provided a perfect fit for the studies. Intraparticle diffusion was also used to investigate the kinetic mechanisms. Intraparticle diffusion was a significant parameter in the regulation of adsorption. The thermodynamic parameters suggested a spontaneous endothermic reaction. The results suggest that WS is an inexpensive adsorbent for effective removal of CV.
