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.
