Abstract: Sample pretreatment is an important process in environmental analysis, which directly influences the accuracy of analysis and strongly determines the detection limits of target pollutants. Magnetic solid phase extraction (MSPE) is a novel technology for sample pretreatment with the advantages of easy operation, short consumption time and low cost. MSPE overcomes the shortages of conventional column-type solid phase extraction (SPE) and thus has been widely applied in the fields of environmental, chemical, biological and pharmaceutical analysis. In this paper, the technology and process of MSPE are introduced and the current status of application of various magnetic materials in the process of enrichment and separation of trace pollutants is summarized. Moreover, the advantages and disadvantages of magnetic particles with different surface modification materials are compared and analyzed. Finally, orientation of MSPE study in the future is discussed.
