Abstract

Abstract

Dye effluent discharge into water bodies leading to water pollution. Each textile dye process requires a different amount of dye and also it generates a different amount of effluents. Most of the physico-chemical methods are insufficient and highly expensive. Biosorption is an alternative technology for the treatment of different textile and other effluents. Aquatic plants specially water hyacinth showed a greater potential to use as biotrap for textile effluent treatment. Both living and dead biomass were tested for the removal of Brown GR textile dye and observed that up to 69.39% dye was removed from its aqueous solution. The adsorption was found monolayer as indicated from the Langmuir model. From the Freundlich model, Temkin model and D-R model it was found that the process was chemical adsorption for living biomass and physical adsorption for dead biomass. Thermodynamic parameters indicated that the adsorption process here is endothermic and is accompanied by the decrease in the randomness. FT-IR data showed the involvement of amine and C=N group for dye biosorption by living and dead biomass, respectively.
