STUDY ON ADSORPTION CAPACITY OF METHYLENE BLUE AND METHYL ORANGE ON MODIFIED LATERITE MATERIAL

Abstract

    This paper focus on the adsorption of Methylene blue and Methyl orange in aqueous solutionon modified laterite material. The material was modified by Fe3+ and SiO32- solution withapatite ore additional cerium. The isoelectric point of the material is 5.91. The experimentswere conducted using the following parameters: quilibrium time is 180 minutes for Methyleneblue and Methyl orange; adsorbent mass is 0.1 g; pH is 7.0 for Methylene blue, 1.0 for Methylorange. Adsorption capacity for each aqueous solution was found as 55.56mg/g (Methyleneblue), 66.67mg/g (Methyl orange) at 250C, respectively. The results indicated that the flowspeed of 1.0mL/min is the best for adsorbing Methylene blue and Methyl orange.
