Abstract
This paper describes the removal of Reactive Blue 114 dye from aqueous solutions by using pomelo (Citrus grandis) peel. Pomelo peel can be described as a new, low cost, abundantly available adsorbent. The optimum adsorbent mass, dye concentration, contact time and pH were determined in this study. The parameters of Langmuir, Freundlich and Temkin adsorption isotherms were also obtained using concentrations of the dyes ranging from 1.0 to 200mg/L. Maximum adsorption capacity was obtained as 16mg/g at pH 2 and 303K solution temperature. The adsorption process was observed to be reaching equilibrium after about 90min.
