摘　　要：近年来,各种污染物通过多种途径进入土壤环境中并积累,对土壤环境质量、食品安全和人体健康产生极大的危害。土壤基质较为复杂,采用高效、选择性好、灵敏度高、便捷简单的前处理技术对土壤中的污染物进行分析检测尤为重要。磁性固相萃取技术作为一种新型的前处理方法,与传统前处理技术相比具有多种优势。随着磁性纳米材料的兴起,根据土壤中污染物的不同,通过对磁性纳米粒子进行功能化修饰可以得到不同吸附性能的吸附材料,从而对土壤中的各种污染物进行选择性吸附。梳理了土壤中存在的主要污染物、传统的前处理技术、磁性固相萃取技术简介及优势,详细阐述了磁性固相萃取技术在土壤污染物分析检测中的应用研究进展,为磁性固相萃取技术在土壤污染物实际检测应用中提供参考。In recent years,various pollutants have entered the soil environment through various ways and accumulated,posing a great threat to soil environmental quality,food safety,and human health.The soil matrix is relatively complex,and it is particularly important to use efficient,selective,and convenient pre-treatment techniques to analyze and detect pollutants in the soil.Magnetic solid-phase extraction technology,as a new pre-treatment method,has multiple advantages compared to traditional pre-treatment techniques.With the rise of magnetic nanomaterials,according to the different pollutants in the soil,functional modification of magnetic nanoparticles can obtain adsorption materials with different adsorption properties,thereby selectively adsorbing various pollutants in the soil.The article summarized the main present pollutants in the soil,traditional pre-treatment technologies,brief introduction and advantages of magnetic solid-phase extraction technology,and elaborated on the application research progress of magnetic solid-phase extraction technology in soil pollutant analysis and detection,providing reference for the practical application of magnetic solid-phase extraction technology in soil pollutant detection.
