In light of the principle of vanadium's valent state change,after samples are dissolved by weak nitric acid,in medium of around 15% nitric acid,the oxidant ammonium persulphate is immediately used to selectively oxidize V~(4+) to V~(5+).

With industrial monomer solution of dimethyldiallylammonium chloride(DMDAAC) as raw material,ammonium persulphate(APS) as initiator and Na_4EDTA as chelating agent,using the methods of adding initiator all at once,graduated increasing of temperature and stepwise initiation and polymerization,the polymerization process of preparing poly-dimethyldiallylammonium chloride(PDMDAAC) was researched.

Poly-dimethyldiallylammonium chloride(PDMDAAC)was prepared by using industrial dimethyldiallylammonium chloride(DMDAAC)aqueous solution with known impurities as starting material,ammonium persulphate(APS)as initiator,without addition of any transferring and terminating agents.
