Abstract

A low-cost adsorbent was prepared from banana peel and adsorption of textile dye Reactive Yellow 15 by the adsorbent was examined. Batch adsorption test showed that extent of dye adsorption was dependent on dye concentration, contact time and pH. Equilibrium adsorption was attained in 180 min and maximum adsorption occurred at pH 2. Adsorption capacity of the banana peel adsorbent for the reactive dye was evaluated by batch equilibrium test. The adsorption data at optimum pH 2 was well described by the Langmuir and Freundlich isotherm models. Langmuir constants Q° and b were 19.76 and 0.22, and Freundlich constants Kf and 1/n were 4.39 and 0.54, respectively. Adsorption of Reactive Yellow 15 by the banana peel adsorbent followed pseudo second-order kinetics. Banana peel is an effective adsorbent for removal of reactive dye from aqueous solution.
