Dye Removal by Adsorption Using Waste Biomass: Sugarcane Bagasse

Dye removal from industrial effluents is an important environmental concern. Various physical and chemical treatment methods can serve this purpose, of which the most economical and effective one is adsorption. A variety of adsorbents are available naturally- rice husk, neem bark, clays etc. that can be used to remove dye from the discharged waste. In this study, adsorption efficiency of low cost adsorbent Sugarcane Bagasse is examined. The effect of different parameters like contact time, adsorbent dosage, initial concentration of dye, pH on the adsorption rate. The data perfectly fits Freundlich isotherm with second order kinetics.
