dc.description.abstractAdsorption of methylene blue, malachite green and nylosan blue dyes onto carbonized coir pith from aqueous solutions was studied. Adsorbent was prepared by carbonizing coir pith at 700 C for l hr. Batch experiments showed that solution pH and adsorbent dose affects the adsorption capacity. The adsorption capacity was highest at solution pH 2 for nylosan blue and above pH 5 for methylene blue and malachite green. The kinetic data fits to second order model. The equilibrium data were satisfactorily fitted to Freundlich isotherm.
