Chitosan has good biological compatibility and degradability. It has good affinity to metallic ion dyes and protein for its rich hydroxyl and amino groups contained in its molecular chain. It is widely applied in the bio-engineering, medicine, food, chemical industry and environment fields, etc. Biomacromolecule coated with nanomagnetic material （including Fe203 and Fe304） has good magnetic conductivity and compatibility so that it can be combined with many kinds of functional polymers like protein, nucleic acid and the biological element and so on. This article reviewed the preparation of chitosan based magnetic materials and its application in adsorption of dyes, heaw metal ion, and protein in waste water. In the end, the application prospect of chitasan, based magnetic materials was presented in this paper
