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.
