Investigation of the Availability of Apricot Shell in Adsorption Equilibrium Studies
Abstract
In this study, adsorption of Cu+2ions from aqueous solution onto apricot stone shell as investigated. First the physicaland chemical characterization of apricot shell was performed, and then the effect of some working conditions on bisorbtion yield was investigated. The fit of the equilibrium results to the adsorption isotherms of Langmuir, Freundlichand Dubinin–Radushkevich (D–R) to data was examined, and it was determined that the best fitted model is Langmuir isotherm.
