Cation Exchangers TRIZ Cases
- Integrated Lithium Recovery with pH-Controlled Sorbent Exchange
Maintaining pH above 5 supports lithium-selective ion exchange, while carbonate removal and water evaporation improve solution purity and recovery.
- Mixed-Oxide Lithium Adsorbent Synthesis for Stable Brine Extraction
Dopant-stabilized titania creates a porous adsorbent for selective, durable lithium recovery from brines.
- Phosphonate Ion Exchanger Regeneration Using Organic Acids
Organic acids regenerate phosphonate ion exchangers by displacing trivalent metal ions, lowering silicon production costs.
- Polymeric Ion Conductor Thermal Stability
Composite polymer structures maintain proton conductivity at high temperatures, preventing decomposition in harsh oxidizing fuel cell environments.
- Doubly-crosslinked hydrogels via metal coordination
Metal coordination crosslinks boost compressive moduli in doubly-crosslinked hydrogels, resolving low mechanical strength.
