Abstract
The effects of water-soluble polymers on the concentration and separation of the aqueous solutions of the metal ions have been studied. EC-PEG 4000 alloy membrane was used as a filter for the concentration and separation of metallic ions. The permeability of this alloy membrane was studied, and it was found that it is iermeable to $Cu^ {2+}$ and $Ni^ {2+}$ but not to $Fe^ {3+}$ ions. The separation of metal ion pairs was performed by using this property of alloy membranes. In this study, the concentration of metal ions ($Cu^ {2+}, Ni^ {2+}, Fe^ {3+}$) and the separation of metal ion couples have been recorded by using polyethyleneimine (PEI) at different pH values and polymer concentrations in accordance with the spectrophotometric results.
