Abstract
The present disclosure relates to a system for recovering multiple kinds of ions, which includes: an ion adsorption tank that includes a plurality of adsorption channels arranged in parallel and including a first electrode unit electrically adsorbing only negative ions and a second electrode unit having an adsorbent layer for adsorbing positive ions to be recovered from positive ions, in which electricity is independently supplied to the adsorption channels; a water tank that keeps liquid discharged from the ion adsorption tank; a pump that circulates mother liquor or liquid stored in the water tank; and an ion recovering tank that keeps liquid containing positive ions to be recovered. According to the present disclosure, a series of processes make it possible to continuously recover ions to be recovered, so the operation efficiency of the system can be maximized.
