Description of the Invention: [Technical Field] The present invention relates to a chitosan fiber and a preparation method thereof, and more particularly to a chitosan fiber containing magnetic particles and a preparation method thereof. [Prior Art] Chitin is a linear polymer saccharide polymer similar to cellulose, which is widely distributed in nature. The outer shell of the crustacean, the outer molt of the arthropod, the outer shell and the inner skeleton of the mollusk, and the cell walls of microorganisms such as fungi or yeast all have chitin. Generally, about 30% of protein, calcium carbonate and chitin are contained in shrimp and crab shells. The use of dilute alkali to remove protein and dilute acid to eliminate carbonic acid can produce relatively pure chitin. Further, the purified chitin is subjected to deacetylation treatment to form chitosan. Chitosan is known to chelate with many heavy metal ions such as copper, cadmium, zinc, uranium ions and the like. Moreover, chitosan itself has biodegradable properties and does not cause secondary pollution. However, the chitosan used in the prior art has reached a limit for the adsorption capacity of heavy metals. Those skilled in the art have long pondered all possible ways to improve the limits of chitosan's ability to adsorb heavy metals, such as the modification of chitosan, but have not yet achieved results. As mentioned above, there is a need in the industry for a way to improve the adsorption capacity of chitosan for heavy metal ions to improve the overall efficiency of the adsorption of heavy metals by chitosan. 5 201005145 SUMMARY OF THE INVENTION The object of the present invention is to improve the adsorption capacity of chitosan for heavy metal. (IV) The object of the present invention is to provide a chitosan composite fiber containing magnetic particles. A preparation method comprising at least the following steps. First, a batch of a brewing solution is prepared. Then, a plurality of magnetic particles are uniformly dispersed in the t-butanose solution. The chitosan solution is wet-spun, and φ is a chitosan composite fiber containing magnetic particles. Another object of the present invention is to provide a chitosan composite fiber having a preferred heavy metal adsorption capacity compared to prior chitosan fibers. According to a preferred embodiment of the present invention, a chitosan composite fiber containing magnetic particles is proposed. The chitosan composite fiber containing magnetic particles contains a plurality of magnetic particles and chitosan fibers. The magnetic particles are uniformly dispersed in the interior and surface of the chitosan fiber in a non-covalent manner. Further, the content of the magnetic particles is 1 to 3% by weight of the chitosan fiber. > Another object of the present invention is to provide an effective heavy metal adsorption method. According to a preferred embodiment of the invention, the method of adsorbing heavy metals comprises the following steps. First, a chitin polymer-containing composite fiber containing magnetic particles according to a preferred embodiment of the present invention is impregnated into a solution containing a heavy metal. Then, a magnetic field is applied to the solution containing heavy metals, so that the magnetic particles are transmitted through a magnetic field to increase the adsorption amount of the chitosan fibers to the heavy metals. The magnetic particles of the chitosan composite fiber containing magnetic particles provided by the present invention can enhance the adsorption amount of chitosan to heavy metals under the action of a magnetic field. 201005145 [Embodiment] I. Preparation method of chitosan composite ruthenium containing magnetic particles The present invention provides a preparation method of chitosan composite fiber containing magnetic particles. In the preparation method, the magnetic particles are uniformly dispersed in the chitosan solution, and the chitosan solution is solidified into a chitosan composite fiber by wet spinning. Among them, the magnetic particles in the chitosan composite fiber after curing are uniformly distributed inside and on the surface of the chitosan fiber. The chitosan solution described above dissolves the chitosan powder in a dilute acid solution. The dilute acid solution may be a citric acid solution, an acetic acid solution, a lactic acid solution, a propionic acid solution or a malic acid solution. The above-mentioned wet spinning uses a spinning nozzle having a hole having a pore diameter of about 0.2 to 0.3 μm. Please refer to Table 1, which is the reactant composition of the chitosan composite fiber containing different magnetic particles of the present invention. Further, the preparation method of the present invention will be described in detail below by means of the respective examples, but the present invention is not limited to the description of the following examples.
