Preparation of insoluble cationic starches and their use in heavy metal anion removal

A series of water‐insoluble anion exchange starches were prepared by the the reaction of various cationic monomers with highly crosslinked starches. These starch products contain tertiary amine and quaternary ammonium functionalities which are effective in removing chromate, dichromate, ferrocyanide...

Zusammenfassung:A series of water‐insoluble anion exchange starches were prepared by the the reaction of various cationic monomers with highly crosslinked starches. These starch products contain tertiary amine and quaternary ammonium functionalities which are effective in removing chromate, dichromate, ferrocyanide, ferricyanide, molybdate, permanganate, and other heavy metal anions from industrial waste effluents. The binding capacity of these anion exchange starches is similar to that of commercial macroreticular resins.
