1. 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 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;
putting a phosphorous supplying material in the lithium-containing desorption solution to obtain lithium phosphate;
removing impurities in the lithium-containing desorption solution before the step of putting a phosphorous supplying material in the lithium-containing desorption solution to obtain lithium phosphate,
wherein the concentration of lithium comprised in the lithium-containing desorption solution is in the range of 0.8 g/L to 1.5 g/L.
