The present invention relates to a hydrogel adsorbent having selectivity to metal ions and a method for preparing the same, and more particularly, to a method for preparing a hydrogel adsorbent having a metal ion selectivity, Lt; / RTI > Injecting the dispersed phase solution into a moving continuous phase solution to prepare a droplet of the dispersed phase solution; And preparing a hydrogel adsorbent by irradiating the droplet with UV light, and a method for producing the hydrogel adsorbent. As a result, the hydrogel adsorbent can effectively adsorb and desorb metal ions, particularly lithium ions, present in the water phase such as seawater and wastewater, so that lithium ions can be recovered with high efficiency. |
