Method for Removing Textile Dyes from Contaminated Water

A highly tunable material that can remove selective dyes from aqueous solutions

Background

Dyes are used in multitude of products in the textiles, pharmaceuticals, cosmetics, food packaging, plastics, pulp and paper, paint, and leather industries. A significant volume of dyes is released to the environment every year from industrial processes. The textile industry uses large proportion of dyes and generates high volume of dye-effluents. It has been estimated that about one million ton of dyes are annually lost to the environment from the textiles industry alone due to inefficient dyeing and finishing operations and untreated effluents. The presence of dyes in water sources causes severe water pollution including a significant alteration in ecological conditions of aquatic life. The impact includes decrease in light penetration through water, which directly affects the photosynthesis of
