Metal-organic frameworks-polymer fiber-based adsorbent forming a core-shell structure and its manufacturing method, and rare earth metal recovery method

Abstract

The present invention relates to a metal-organic framework-polymer fiber-based adsorbent having a core-shell structure and a method for preparing the adsorbent, and a method for recovering a rare earth metal using the same, which result in having easy recovery of the adsorbent together with excellent characteristics of a maximum adsorption amount and an adsorption rate for the rare earth metal. The metal-organic framework-polymer fiber-based adsorbent having the core-shell structure according to the present invention is characterized in that the metal-organic framework is provided on a surface of a sodium polyacrylate (NaPA) fiber.
