Adsorptive Removal of Methylene Blue by Ginkgo Leaf Powder
The adsorption of methylene blue (MB) from aqueous solution using a low-cost adsorbent, ginkgo leaf powder, has been studied. The equilibrium data were fitted to Langmuir and Freundlich isotherms and the equilibrium adsorption was best described by the Langmuir isotherm model with maximum monolayer adsorption capacities found to be 39 mg/g. The sorption was analyzed using pseudo-first-order and pseudo-second order kinetic models, and the sorption kinetics was found to follow a pseudo-second order kinetic model. Ginkgo leaf appears as a prospective adsorbent for the removal of methylene blue from aqueous solution.
