The Permeability of Polyester Film (PEN) to Copper Ions

Abstract

Ion exchange membranes (IEM) are often applied in the processes of separation and purification solutions, primarily in the chemical, food, and pharmaceutical industries. Most are currently made from organic polymers, such as polyamide and polyimide. In this work, a study of the permeability of polyethylene naphthalate film (PEN) to copper Cu(II) (heavy metal), using the Donnan dialysis technique, has allowed us, first, to highlight a new anion exchange membrane (AEM), and second, to improve its capabilities for the elimination of copper ions after heat treatment.
