Abstract
In textile sector uses a huge volume of water and chemicals, including inorganic compounds, polymers, and organic products. Textiles effluents including different types of dyes like acidic, reactive, basic, disperse, azo, diazo, anthraquinone and metal-complex dye. Textile effluents create chronic ecological problems due to their toxicity, pernicious and carcinogenic characters and, at present, purification process of textile effluents is a critical problem for society. Biosorption process through water hyacinth biomass as a fructuous and inexpensive process for the expel of dyes from textile industrial colorants. In the present study, biosorption of basic fuchsin dye was carried out using different doses of the dried and powdered biomass of water hyacinth. The dose of plant biomass (50mg to 400mg) observed high percentage of adsorption at 20 ppm dye concentration. The results of Freundlich adsorption isotherm showed a better biosorption than Langmuir adsorption model. FTIR spectra of the unloaded and dye loaded biomass showed the change in the surface chemistry of the biosorbent and predicted the role of C=N (Very StrongVS), C=S (Strong- S), CH2 (Strong-S), CH=CH (Strong- S) groups in the removal of basic fuchsin dye from the aqueous solutions.
