Abstract
An environment eco-friendly adsorbents such as filtrasorb-816 and filtrasorb-820 were used in this work. For the evaluation of the adsorption of manganese from the aqueous phase, granular activated carbons were used in conjunction with organic ligands such as 3,5-Dinitrobenzoic acid. The phenomenon of adsorption characteristics of manganese in an aqueous phase was studied at a constant temperature of 25 ±1℃ C and pH 5. Granular activated carbons were characterized by SEM analysis. Experimental data were tested by using Pseudo first and Pseudo second-order kinetic models. From the results, it was investigated that Pesudo second-order data is more favorable than the pseudo-first-order for this system. The Langmuir, Freundlich, and Temkin isotherms models were used to describe the equilibrium characteristics of adsorption of Mn2+ onto activated carbon but the R2 value of the Langmuir isotherm model was higher than other isotherms and hence it is the best fit. From this study, it was found that F-820 has more adsorption capacity to scavenge Mn2+ than F-816 from aqueous phase
