Textile industries utilize huge quanty of water and resultantly,
large volume of waste effluents is produced. The coloured water
along with dyes, auxilliries and salts are discharged into water
without ant treatment [1]. Therefore, development of wastewater
treatment methods is imperative to avoid the environment
contamination of dyes [2,3]. Over 50,000 tons of different synthetic
dyes are annually produced and approximately up to 10% are mixed
with water bodies. Even at low concentrations in water, dyes are
detectable and have an inhibitory effect on the photosynthesis
process, and thus affecting the aquatic ecosystem. Due to synthetic
origin and complex molecular structure, dyes are resistant to
biodegradation when released in to the environment and their
incomplete degradation often produces toxic by-products. Many
chemical, biological and physical methods have been tried for the
removal of dyes from wastewater [2–20].
