The adsorption of cyanocobalamine was studied using coal-based mesoporous activated carbon (AC). The ACs tested showed a comparable pore volume, around 0.5cm 3 g −1 , but different contribution of mesopores ranging from 0.53 to 0.82cm 3 g −1 . The adsorption of cyanocobalamine was carried out in slightly alkaline solution in static conditions. Three kinetic models including...
