| Outline of Final Research Achievements |
Optimizing the calcination of biomineralized manganese oxides, biotemplated lithium ion sieve was successfully synthesized, which has the maximum adsorption capacity of 14.7 mg-Li/g-MnOx. Fabrication of powdery biotemplated lithium ion sieve in alginate beads improved the handleability. After fabrication, the maximum adsorption capacity and recycability were still maintained, although the adsorption kinetics decreased. Fabrication of powdery biotemplated lithium ion sieve in alginate beads largely contributed to separation and recovery of lithium from natural waters including geothermal and sea waters.
