Decolonization of Textile Dye (Cl Direct Hlue 201) by Selected Aquatic Plants

Abstract

Attached

Untreated or partially treated textile dye effluents present a significant environmental and health problem as those are finally end tip into aquatic environment. Textile industry has received greater attention from national and international agencies as major pollutant source of water and to find out solutions to control or minimize water pollution. Present study was aimed to determine ability of some aquatic plants to use for Cl Direct Blue 201 textile dye decolorization. Therefore lour aquatic plants namely Eichhomiu cnissipes (water hyacinth), l.cmnu sp. (duckweed), Snlviniu sp. ( watermoss) and Pistiu sp. (water lettuce) were employed in the present study and complete decolorization was recorded by E. cnissipes at 2 days of treatment where Pistiu sp. showed complete decolorization at 8 days. After 14 days, decolorization percentage of Snlviniu sp. and l.einnu sp. were reached as 79.33 ± 2.01% and 16.47 ± 1.95 % respectively. Further, root extract of E. Cnissipes revealed that some chemical compound present in roots may have a potential effect on decolorization of the textile dye. Studies on photolysis effect on the decolorization of Cl Direct Blue 201 dye was not showed any effect. Thus, the results of present study showed that E. cnissipes is a potential aquatic plant which could be employed as a low cost alternative candidate to remove Cl Direct Blue 201 from textile waste water.
