Summary: | Magnetic nanomaterials are a new kind of nanomaterials with great potential application value. Recently, there have been many reports about the combination of magnetic nanomaterials and agricultural residue detection technology to establish a new detection method. Due to the special super paramagnetic, the large number of surface active sites, easy separation and recovery, the Fe

magnetic nanocomposite material is commonly used in complex sample pretreatment on extraction and enrichment of the target compounds. By combining with the target substance in complex sample matrix and under the action of external magnetic field, the material can quickly, simply and efficiently enrich and extract trace substances in the sample. This paper mainly introduces the application of Fe
