Equillibrium Modelling of Adsorptive Removal of Methylene Blue Using BGA

Abstract

The removal of Methylene Blue dye from aqueous solution using a biowaste, dried Blue Green Algae was investigated in terms of variation of initial concentration of the dye solution, adsorbent dosage and pH. The optimum pH for the removal of dye by adsorption was found to be pH 7. The data obtained in this study fitted with Langmuir and Freundlich adsorption isotherms. The experimental data confirms the monolayer adsorption capacity of the adsorbent.
