Removal of Methylene Blue Methyl Violet Acid Blue and Acid Violet using Blue Green Algae by Adsorption Technique

Abstract

Environmental pollution is a major concern due to the toxic nature of the industrial effluents discharged into natural water resources Synthetic dyes are used extensively in textile, paints cosmetics plastics pharmaceutical pulp and paper and tannery industries These industries generate high amount of wastewater It is estimated that 10 to 15 percentage of the dyes lost in the dye effluent during newlinedyeing process Chen et al 2011 Dyes once enter the water it is no longer good and difficult to treat as the dyes have a synthetic origin and a complex molecular structure which makes them more newlinestable and difficult to be degraded Algae a renewable natural biomass proliferates ubiquitously and abundantly in the littoral zones of water Advantages using algae as an adsorbent include the wide availability lowcost and high adsorption capacity In the view of the above facts the present work is aimed to study the removal of Methylene Blue Methyl Violet Acid Blue and Acid Violet dyes from aqueous solution and also from industrial effluent using Blue Green Algae by adsorption technique
