Ferrocenes
Ferrocenes are good redox compounds.
The monomer vinyl ferrocene is added into the polymerization kettle, and azoisobutyronitrile is used as the initiator.
Other types
Use polystyrene for nitration and reduction to obtain amino polystyrene
After the polystyrene is nitrated by nitric acid in the nitration kettle, sodium sulfide and sulfur powder are added to heat to reduce it to p-amino polystyrene
(7) Utilize the exchange functional groups of general ion exchange resins to exchange with ions with redox ability through ion exchange, so that the resins are equipped with redox groups and then used
① Cationic resins such as tricarboxylic acid or sulfonic acid, phosphoric acid and other cationic resins with Cu 2+ , Sn 2+ , Hg 2+ , Fe 2+ , Co 2+ , Ni 2+ , Mn 2+ and NH 2 -NH 2 etc.
② anion resin with SO .
