Adsorption of Copper Using Pomelo Peel and Depectinated Pomelo Peel

Penpun Tasaso
Abstract—The removal of Copper (Cu2+) from aqueous solution by adsorption on pomelo peel (PP) and depectinated pomelo peel (DPP) were studied. Factors affected to adsorption; initial pH, initial concentration, contact time and temperature were investigated. It was found that the highest Cu2+ adsorption capacity for PP and DPP were 19.7 mg/g and 21.1 mg/g at the following conditions; pH = 4 , 125 mg/l of initial concentration , temperature of 25 0C and equilibrium time about 60 min. Adsorption isotherm of both PP and DPP were well described by the Langmuir model. The kinetic studies showed that a pseudo-second-order rate model was adopted to described the Cu2+ adsorption. The thermodynamics parameter of the Cu2+ adsorption were evaluated at temperature of 25, 35 and 45 0C. The negative of standard free energy change and enthalpy change revealed that the adsorption process is spontaneous and exothermic.

Index Terms—Adsorption, copper, kinetics, pomelo peel.
