Title:
APPARATUS AND METHOD FOR ADSORBING AND DESORBING LITHIUM IONS USING A CCD PROCESS
Document Type and Number:
WIPO Patent Application WO/2012/070769
Kind Code:
A1
Abstract:
Disclosed is a method for adsorbing/desorbing lithium ions, which can attain an adsorption rate of 65±5% and a desorption rate of 95±3% by performing an absorption process and a desorption process using a CCD process. According to the present invention, the method for adsorbing/desorbing lithium ions using a CCD process is characterized by including: a step of supplying saline solution into one of a plurality of adsorption reaction containers; a step of enabling the adsorbent material to adsorb the lithium ions by introducing an adsorbent material into the adsorption reaction container containing the saline solution, and enabling the saline solution and the adsorbent material to sequentially flow backward along each of the insides of the plurality of adsorption reaction containers; and a step of desorbing the lithium ions from the adsorbent material by enabling the adsorbent material adsorbing the lithium ions to flow backward along the inside of each of a plurality of desorption reaction containers.
