Method for removing arsenic from Antarctic krill oil

The invention relates to the technical field of aquatic product processing. In order to solve the problems that a traditional method for removing arsenic in Antarctic krill oil is complex and an adsorbent is hard to remove, the invention provides a method for removing arsenic in Antarctic krill oil. The method comprises the following steps: dispersing Antarctic krill oil in an organic solvent, adding EDTA (ethylene diamine tetraacetic acid) grafted magnetic chitosan, performing an ultrasonic oscillation reaction, and removing the EDTA grafted magnetic chitosan, so as to obtain Antarctic krilloil of which arsenic is removed. By adopting the method, EDTA grafted magnetic chitosan microspheres are adopted to efficiently adsorb and remove the arsenic from the Antarctic krill oil, the materialhas the advantages of being environmentally friendly, easy to separate, long-lasting in application, and the like, the application of the Antarctic krill oil of which the arsenic is removed can be widened, and the security of
