The objective of this work is the study of adsorption of dye solution of three dyes (crystal violet, methylene blue & malachite green) using chlor-alkali waste. Removal of these dyes from aqueous solution using chlor-alkali waste 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 initial concentration. Adsorption capacity of chlor-alkali waste is determined for competitive adsorption of dyes. Optimum conditions for dye removal are studied like pH value, contact time required, amount of adsorbent, initial concentration, etc. Dyes are present in various Industrial effluents like Textile Industries, Sewage water, Water treatment plants. This work can have use in Design of adsorption setup for dyes removal.
