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.
