ADSORPTION CAPACITIES OF LOW-COST ADSORBENT OF ACTIVATED CARBON MERREMIA EMARGINATA FOR REMOVAL OF METHYLENE BLUE

Abstract

In this research, the adsorption behavior of Methylene Blue dye from synthetic aqueous solution onto Activated Carbon Merremia Emarginata (ACME) was investigated. The effect of crucial parameters such as agitation time, pH, adsorbent dosage and other ionic concentration was studied. The equilibrium isotherm models, thermodynamic parameters and kinetic data have been evaluated. Adsorption equilibrium isotherms were expressed by Freundlich and Langmuir adsorption models and it was found that Langmuir adsorption model fits the experimental data better than Freundlich model. The adsorption can be best described by the pseudo second-order kinetic model. The objective of the present work suggests the ACME may be utilized as a low cost adsorbent for Methylene Blue dye removal from synthetic aqueous solution.
