ION-EXCHANGE TYPE LITHIUM ADSORBENT USING CERAMIC FILTER AND METHOD FOR PREPARING THE SAME

摘要

An ion-exchange type lithium adsorbent using a ceramic filter and a method for preparing the same easily and simply are provided, wherein the ion-exchange type lithium adsorbent is physically and chemically stable, is easily handled, and is excellent in adsorption performance capable of selectively adsorbing lithium ion only such that the adsorbent adsorbs and recovers lithium efficiently. A method for preparing an ion-exchange type lithium adsorbent using a ceramic filter comprises the steps of: synthesizing a precursor powder that is a lithium manganese oxide with a spinel structure; filling the precursor powder in a ceramic filter; and acid-treating the precursor powder-filled ceramic filter. A method for preparing an ion-exchange type lithium adsorbent using a ceramic filter comprises the steps of: synthesizing a precursor powder of the chemical formula LinMn2-xO4 with a spinel structure, wherein n is ranged from 1 to 1.33, x is ranged from 0 to 0.33, and n is less than or equal to 1+x; filling the precursor powder in a ceramic filter; and acid-treating the precursor powder-filled ceramic filter. An ion-exchange type lithium adsorbent using a ceramic filter comprises an ion exchange type manganese oxide powder with a spinel structure filled in a ceramic filter. An ion-exchange type lithium adsorbent using a ceramic filter comprises an ion exchange type manganese oxide powder of the chemical formula HnMn2-xO4 with a spinel structure filled in a ceramic filter, wherein n is ranged from 1 to 1.33, x is ranged from 0 to 0.33, and n is less than or equal to 1+x.
