Multi-cycle operations for Lithium Extraction-insertion in the Spinel Manganese Oxide Adsorbents

摘要

The results showed that the extraction-insertion of lithium for spinel-type adsorbent was proceeded via redox mechanism. Multi-cycle operations resulted in the lowering of the lithium adsorptivity and collapse the spinel structure. Work on finding eluents with higher Li uptake and less Mn dissolution is now in progress.
