Abstract:

Spinel type lithium manganese oxides (LMOs) are promising adsorption materials for selective recovery of lithium from salty brines. In this work a lithium-ion sieve material, H1.6Mn1.6O4, derived from Li1.6Mn1.6O44, a spinel type LMO, was successfully prepared via hydrothermal synthesis. This lithium-ion sieve, H1.6Mn1.6O4, was then used in laboratory tests to adsorb Li+ from a generic LiCl solution and geothermal brine from Bruchsal geothermal power plant. Desorption experiments were performed with the following desorption solutions: ammonium peroxydisulfate ((NH4)2S2O8), sodium peroxydisulfate (Na2S2O8), acetic acid (CH3COOH), sulfuric acid (H2SO4), carbonic acid (H2CO3), ascorbic (C6H8O6) and hydrochloric acid (HCl). The results showed that C6H8O6 led to adsorbent destruction and only small amount of lithium was desorbed with H2CO3. CH3COOH and (NH4)2S2O8 showed the best desorption performance with high lithium recovery and low Mn dissolution. The kinetic experiments indicate that more than 90% of equilibrium was reached after 4 hours. ... mehr
