Method for manufacturing electrode module for recovery of metal ions, electrode module for recovery of metal ions, and apparatus for recovery of metal ions including the same

摘要

The present invention relates to a method for manufacturing an electrode module for recovery of metal ions, an electrode module for recovery of metal ions, and an apparatus for recovery of metal ions including the same. The present invention provides a method for manufacturing an electrode module for recovery of metal ions, the method including the steps of: a) preparing a first electrode part and a second electrode part for electrically adsorbing or desorbing metal ions contained in a liquid; and b) interposing an insulating layer, through which the liquid passes, between the first electrode part and the second electrode part, an electrode module for recovery of metal ions manufactured by the method, and an apparatus for recovery of metal ions including the same. According to the present invention, it is possible to significantly reduce the time required for the adsorption and desorption of ions when specific valuable metal ions are recovered from an aqueous solution in which various valuable metal ions are dissolved.
