Adsorption of Methylene Blue by Activated Carbon from Coconut Sawdust
Abstract
In this work, activated carbon from coconut sawdust were prepared using phosphoric acid as chemical activating agent under impregnation ration of 1:1.5 (wt : wt) of phosphoric acid and sawdust at temperature 550oC and 60 min. A BET surface was examined in a range of 715-743 m2/g. Batch adsorption capacities of methylene blue on the coconut sawdust with respect to the initial dye concentration, pH and temperature were investigated and analyzed to the kinetics adsorption and its isotherm. The kinetic models of the pseudo first order and the pseudo second order were analyzed. Kinetic studies showed that the kinetic data were well described by the pseudo second order kinetic model. Also the experimental data were investigated using Langmuir and Freundlich isotherm model. It showed that both isotherms were well fitted based on the coefficients of determination R2.
