Competitive Adsorption of Dyes(congo red, methylene blue,malachite green) on Activated Carbon

Abstract

The objective of this work is the study of adsorption of dye solution which is a mixture of three dyes (methylene blue, congo red & malachite green) using commercial activated carbon.Removal of these dyes from aqueous solution using commercial activated carbon has been
investigated. Liquid phase adsorption experiments were conducted. Batch adsorption studies are carried out by observing the effect of experimental parameters, namely, pH, amount of adsorbents, contact time and temperature. Adsorption capacity of activated carbon is determined for
competitive adsorption of mixture of dyes. Optimum conditions for dye removal are studied like
pH value, contact time required, amount of adsorbent, temp, etc. The results generated by this project work can be used for determination of optimum conditions for adsorption of mixture of dyes in aqueous solutions. Dyes are present in mixture form in various Industrial effluents like Textile Industries, Sewage water, Water treatment plants. This work can have use in Design of adsorption columns for dyes removal.
