The adsorption of methylene blue (MB) onto activated carbon (AC) derived from coffee husk using zinc chloride activation at 600 oC was studied. The effects of various parameters such as contact time, initial MB concentration and temperature were investigated. The adsorption kinetics of pseudo first-order and pseudo second-order were used for the kinetic studies and were found to follow the pseudo second-order kinetic model. |
