Method of making magnetic, cross-linked chitosan support materials and products thereof |
| abstract |
Method for magnetizing cross-linked chitosan support material involving the treatment of carboxyl group-containing, cross-linked chitosan gels with solutions of ferrous chloride followed by treatment with dilute aqueous alkali and then oxidation with molecular oxygen gas to produce highly-enriched magnetized chitosan particles, beads, films and/or coatings. |
