Title: Metal Scavengers Based on Alkane Diamine and Alkane Dithiol-Modified Poly-1,4-Dihydropyridazines and Polypyridazines

 

Invention: The 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.

 

Applications:

  • Waste removal
  • Toxic manufacturing
  • Water treatment

 

Advantages:

  • 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
