  • ELECTRODIALYSIS CELL AND METHOD FOR LITHIUM SEPARATION
    Publication number: 20250319440
    Abstract: An electrodialysis cell comprises an alternating arrangement of a surface modified cation exchange membrane and an anion exchange membrane. The surface modified cation exchange membrane is lithium selective, and the electrodialysis cell can be particularly useful for recovering lithium or other metals from spent lithium ion batteries or natural salt brines.

  • Surface modification of zero valent iron material for enhanced reactivity for degrading chlorinated contaminants in water
    Patent number: 10640406
    Abstract: Methods, systems, and compounds for degrading chlorinated compounds in water. A facile aqueous-based surface treatment of zero-valent iron is provided to increase the reactivity of a zero-valent iron material for degrading chlorinated compounds in the water without the use of a noble metal catalyst. Such a facile aqueous-based surface treatment can be implemented as a surface sulfidation pre-treatment of iron to increase its reactivity towards chlorinated contaminants in water. The disclosed facile aqueous-based surface treatment increases reactivity utilizing sulfur compounds for use in the degradation of the chlorinated compounds in the water.
