COMPOSITE ELECTRODE FOR RECOVERING COPPER ION AND COMPOSITE ELECTRODE MODULE COMPOSITE ELECTRODE MODULE SYSTEM AND METHOD FOR THEREOF COPPER ION RECOVERING METHOD USING THE SAME

摘要

The present invention relates to a composite electrode for recovering copper ions, comprising a coating layer on one surface or both surfaces of a substrate, wherein the coating layer comprises chitosan, polyvinyl alcohol and a carbon-based conductor. The present invention further relates to a composite electrode module comprising the same, a composite electrode module system, a manufacturing method thereof and a method for recovering copper ions using the same. A composite electrode of the present invention is capable of recovering copper ions with a high recovering rate at low concentrations.
