Abstract

The present invention relates to a method for removing lithium from a lithium comprising solution comprising contacting a lithium comprising solution with an adsorbent comprising an ion-exchange material comprising one or more of Ti, Mn and Zr, thereby obtaining a lithium comprising adsorbent and a lithium depleted solution, and contacting the lithium comprising adsorbent with an elution solution comprising a pH buffer solution configured to buffer the pH of the elution solution at a value between 1.5 and 7, thereby eluting the lithium from the lithium comprising adsorbent into the elution solution, thereby obtaining a lithium comprising elution solution and the adsorbent.
