Abstract

La presente invención se refiere a un método para producir hidróxido de litio. De forma específica, de acuerdo con una forma de realización de la presente invención, un método para producir hidróxido de litio comprende: un paso de preparación de la solución que consiste en preparar una solución de hidróxido de litio que contiene impurezas e iones de litio; un paso de pasaje de la solución de ácido de unión que consiste en hacer pasar una solución de ácido de unión a través de la resina de quelato para permitir que los iones de hidrógeno se unan a la resina de quelato; un paso de pasaje de agua destilada que consiste en hacer pasar agua destilada a través de la resina de quelato para eliminar la solución de ácido de unión restante de la resina de quelato; un paso de pasaje de la solución de hidróxido de litio que consiste en hacer pasar la solución de hidróxido de litio a través de una resina de quelato para permitir que los iones contenidos en las impurezas se unan a la resina de quelato; y un paso de pasaje de la solución de ácido de separación que consiste en hacer pasar una solución de ácido de separación a través de la resina de quelato unida a las impurezas para separar las impurezas unidas al quelato de la resina de quelato.
