Removal of Copper from Water by Decaying Tamrix gallica Leaves

Abstract

Uptake of copper from aqueous solution by Tamrix gallica leaves
has been studied. The effect of several factors on both rate and
amount of this uptake has been investigated. These factors include
concentration of copper, concentration of leaves, pH, competing
ions, drying leaves and grinding leaves.
The pattern of curves showing the loss of copper from solution
has been explained. Applicability of the Freundlich adsorption isotherm
on the present results has been examined and the parameters
of this isotherm have been calculated. The order of reaction between
copper ion and Tamrix gallica leaves has been determined and a
mechanism for this reaction has been suggested.
