Abstract
The present invention relates to a method for producing lithium phosphate, comprising: passing a lithium-containing solution through an aluminum-based adsorbent to adsorb lithium on the aluminum-based adsorbent, passing the distilled water or an aqueous solution having a lower lithium concentration than the lithium-containing solution through the aluminum-based adsorbent on which the lithium is adsorbed to obtain a lithium-containing desorption solution, and putting a phosphorous supplying material in the lithium-containing desorption solution to obtain lithium phosphate.
