Abstract

La presente se refiere a un método para producir fosfato de litio, que comprende: pasar una solución que contiene litio a través de un adsorbente a base de aluminio para adsorber litio en el adsorbente a base de aluminio, pasar el agua destilada o una solución acuosa que tenga una concentración de litio menor que la solución que contiene litio a través del adsorbente a base de aluminio sobre el cual el litio se adsorbe para obtener una solución de desorción que contiene litio; y colocar un material proveedor de fósforo en la solución de desorción que contiene litio para obtener un fosfato de litio.This refers 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 distilled water or an aqueous solution having a lithium concentration lower than the lithium-containing solution through the aluminum-based adsorbent on which the lithium is adsorbed to obtain a lithium-containing desorption solution; and placing a phosphor-supplying material into the lithium-containing desorption solution to obtain a lithium phosphate.
