Adsorption of Three Flavonoids from Aqueous Solutions onto Mesoporous Carbon
A mesoporous carbon adsorbent was synthesized for the adsorption of myricetrin, puerarin, and naringin from aqueous solutions. The mesoporous carbon can effectively adsorb the flavonoids, and the adsorption capacities at the feed temperature of 298 K and equilibrium concentration of 0.05 mgmL(-1) were from 63 to 206 mgg(-1). Adsorption thermodynamic parameters were calculated. Adsorption kinetics and adsorption dynamic breakthrough experiments further confirmed the efficient adsorption of these molecules on the carbon adsorbent. A complex mechanism involving physical adsorption and chemical adsorption was suggested for the adsorption of myricetrin, puerarin, and naringin on the mesoporous carbon.
