Adsorption of Methyl Orange from Wastewater onto Cane Papyrus

Abstract

The aim of the present work is the adsorption of the Methyl Orange dye from wastewater onto Cane Papyrus by using continuous system (fixed bed). Continuous adsorption experiments of fixed bed were carried out to study the effects of (flow rate Q, initial dye concentration C₀, bed depth Z, and PH) on the adsorption capacity and performance of fixed bed adsorber. Adsorption through Cane Papyrus was found to be effective for the removal of the Methyl Orange, where the percent dye removal was 50% and reach 70% for some cases. The equilibrium data were determined experimentally and the equilibrium isotherm was found to be of a favorable type and fit well by Langmuir and Freundlich isotherms. In the kinetics study, pseudo-first order and pseudo-second order were tested; the first equation showed the best represent the experimental data.
