The invention discloses a magnetic carbon nanotube and a method for extracting lean meat essence from pork. The magnetic carbon nanotube Fe3O4@ Cys @ CNT is prepared by from FeSO4.7H2O, L-cysteine (Cys) and carbon nanotubes (CNT) as raw materials. The magnetic carbon nanotube Fe3O4@ Cys @ CNT is used as an adsorbent to extract the lean meat concentrate (ractopamine and clenbuterol hydrochloride) from the pork. The effective enrichment and separation of the lean meat essence in a pork sample to be tested is realized, and the sensitivity of the existing method for detection of the lean meat essence in the pork can be greatly improved. 本发明公开了种磁性碳纳米管及其对猪肉中瘦肉精的萃取方法，本发明以FeSO·7HO、L-半胱氨酸（Cys）和碳纳米管（CNT）为原料，制备得到磁性碳纳米管FeO@Cys@CNT。使用所述磁性碳纳米管FeO@Cys@CNT作为吸附剂，萃取猪肉中的瘦肉精（莱克多巴胺和盐酸克伦特罗），实现了对待测猪肉样品中瘦肉精的有效富集与分离，可大大提高现有猪肉中瘦肉精检测方法的灵敏度。
