Abstract: Several synthetic dyes employed in
textile and food industries are discharged into aquatic environment. These visible
pollutants in water damage environment, as they are carcinogenic and toxic to
humans. The use of cost effective and ecofriendly
plant cellulose based adsorbents have been studied in batch experiments as an
alternative and effective substitution of activated carbon for the removal of
toxic dyes from waste water. Adsorbents prepared from sugarcane baggase, were successfully used to remove certain textile
dye such as crystal violet from an aqueous solution. The present investigation potentiate the use of sugarcane baggase,
pretreated with formaldehyde (referred as Raw Baggase)
and sulphuric acid (referred as Chemically
Activated Baggase), for the removal of crystal violet
dye from simulated waste water. Experiments were carried out at neutral pH with
various parameters like dye concentration, temperature, contact time and
adsorbent dosage. Efficiency of raw baggase was found
better than chemically activated baggase for
adsorption of crystal violet dye. The data obtained perfectly fits in the Freundlich adsorption isotherm. Key
