Complex Ion-Exchangers TRIZ Cases
- Water-Soluble Chelating Polymer for Rapid Trace Heavy-Metal Removal
Ionic bonding of chelating groups to an anionic polymer enables fast capture of trace heavy-metal ions to ppm levels or lower.
- Alkaline Battery Metal Recovery via Leaching and Ion Exchange
Sulfuric acid leaching, hot crystallization, and ion exchange recover manganese and zinc from alkaline battery black with lower energy use.
- Nitrate Ion Detection Using Hydrogen-Bonding Organic Dopants
Hydrogen-bonding organic dopants enable ion exchange detection of nitrate ions with lower background interference and higher sensitivity.
