DECOLORISATION OF NAVY BLUE DYE USING A PLANT BIOMASS -ALBIZIA AMARA (SILK TREE)

Abstract

Textile processing industries discharge enormous amount of chemical compounds mainly dyes into soil and water bodies. It is the major cause of water and soil pollution that results in reducing the soil fertility, plant growth and unregulated and disrupted food chain. Using a plant material to absorb the discharged dye will effectively reduce the contaminant level and biodegradability can be enhanced ecofriendly. In the present investigation, Albizia amara-AA (silk tree or oil cake tree) leaf biomass was used as a natural adsorbent for removal of navy blue dye, commonly employed for coloring fabrics. In order to decide toxicity evaluation of dye, the dye was prepared in different concentrations with a range of 0.25, 0.50, and 1.00%.  Column binding study and FTIR analysis showed that Albizia amara (A A) leaf biomass can bind to navy blue dye and decolorize it upto 1% and the thus obtained remediated soil can be reused for vegetation.
