This invention is a new class of metal ion scavengers that can bind to transition, lanthanide, and actinide metals from water or organic solvents.
About
Metal Scavengers Based on Alkane Diamine and Alkane Dithiol-Modified Poly-1,4-Dihydropyridazines and Polypyridazines Tech ID: UA17-128 Invention: This invention is a new class of metal ion scavengers that can bind to transition, lanthanide, and actinide metals from water or organic solvents. This new class is 3,6-diaminoalkane, dithiolakane substituted 1,4-dyhidropyridazine, or 3,6-dipyri-2-yl-4,5 pyridazine compounds. Background: Resins are important for removing toxic heavy metals from drinking water due to pharmaceutical manufacturing, semiconductor manufacturing, mine effluent, and electrochemical processing. Current resins are limited in capacity and binding activity.
Key Benefits
- Can pick up to 4 mmoles of metal per gram of resin compared to current options which are limited to only 2 mmoles of metal per gram - Allows for flexible preparation such as a coating surface, gel, or a packed bed of resin spherical particles
Applications
- Waste removal - Toxic manufacturing - Water treatment
