Removal of Basic Organic Dyes from Effluent Water of Dyeing and Printing Units Using Some Bio–Adsorbent

Jain J. K, Shrivastava Neha

Abstract :

To remove colouring impurities from the effluent waste water of Sanganeri dyeing and printing units, a green approach has been made. We tried single viz; fine powder of Neem (Azadirachta indica) leaves powder and Blackberry( Syzygium cumini)bark powder as well as their varied proportions as mixed bio–adsorbents. The efficiency to remove colour and certain heavy metals from effluent water, the application of mixed bio–adsorbents proved to be more useful than the application of single bio–adsorbents. The results were justified by the measurement of optical density, conductivity and pH of the effluent water before and after treatment with adsorbents. The effectiveness of adsorption is further justified by Freundlich and Langmuir adsorption isotherms.
