Effect of bio-adsorbents (Strychnos potatorum seed) for elimination of methyl orange dye from polluted waters
The use of cheap, high efficiency and ecofriendly adsorbent has been studied as an alternative source of activated carbon for the removal of dye from wastewater. Bio-adsorbents derived from plant materials of Strychnos Potatorum Seed have been probed for their surface sorption abilities towards Methyl Orange Dye using simulated waters. The parameters studied were the effect of pH, amount of adsorbent, contact time and concentration of adsorbate. Equilibrium data were fitted to the Langmuir and Freundlich isotherm models. The data were best represented by the Langmuir model with an adsorption capacity and adsorption intensity. The adsorption was found to be concentration dependent and the maximum adsorption was occurred in 3 hrs. Thus, from the results of adsorption data, it was concluded that the Strychnos potatorum seed powder was found to be excellent adsorbent for the adsorption of methyl orange dye from industrial waste water.
