The adsorbent was prepared from banana peel and adsorption of Reactive Yellow 15 (RY15) dye by the banana peel adsorbent was examined. Batch adsorption tests showed that extent of dye adsorption was dependent on pH, dye concentration, contact time and adsorbent dose. Equilibrium adsorption was attained in 3 h, with maximum adsorption occurring at a pH value 2 and adsorbent dose of 6 giL. Equilibrium adsorption data were well described by Langmuir and Freundlich adsorption isotherm models. The adsorption of Reactive Yell ow 15 followed pseudo-first-order kinetics. The results indicate that adsorbent prepared from banana peel is effective in adsorptive removal of Reactive Yellow 15. Hence, banana peel would be suitable low cost substitute for commercial activated carbon in the removal of reactive dyes from aqueous solution.
