Study of Adsorption of Methyl Orange and Methyl Violet Dyes on the surface of Triethyl amine glyceryl maleate polymer

Abstract

The adsorption processes of two dye compounds (Methyl orange (MO) and Methyl violet (MV)) in aqueous solutions on the surface of crosslinked Triethyl amine glyceryl maleate polymer were investigated at different temperature, ionic strength and pH. The results revealed that the adsorption of these compounds at (25°C) follow S-mode adsorption according to Giels classification. At fixed adsorpent, the adsorbate quantity of MV more than MO and no different pattern was noticed with regard to the adsorption depending on the ionic strength. Generally, it was noticed that the adsorption quantities is correlated with the pH values of the medium. In addition, it was found that the polymer has higher ability to adsorb the two dye compounds in comparing to zeolite (25A).
