ABSTRACT

 The potential feasibility of activated yam peel (YP) to remove methylene blue from aqueous solution was evaluated in a batch process. Experiments were carried out as functions of contact time, initial concentration (20-250mg/L), pH (4-12), and temperature (303, 313, 323, 333 and 343K). The kinetic data were analyzed using pseudo-first order and pseudo-second order models. The pseudo-second order model with R2 of (1) provided a better description for the adsorption process than the first order. The results indicated that yam peel could be an alternative for more costly adsorbents used for dye removal.
