Lithium recovery with LiTi2O4 ion-sieves

A feasibility study for the recovery of lithium from salt water with the protonated lithium titanium oxide ion-sieves was carried out in this work. Lithium ions (Li+) in LiTi2O4 having a similar ion density with H+ allow repeated exchanges and regeneration with high selectivity. By Li7 magic angle s...

Description
Summary:A feasibility study for the recovery of lithium from salt water with the protonated lithium titanium oxide ion-sieves was carried out in this work. Lithium ions (Li+) in LiTi2O4 having a similar ion density with H+ allow repeated exchanges and regeneration with high selectivity. By Li7 magic angle spinning solid-state magnetic resonance, it is apparent that chemical structure of lithium in the ion-sieves is not perturbed during the repeated Li+/H+ exchange processes. As the dissolution of titanium is negligible (
