摘　　要：作为一种新型非金属材料,石墨相氮化碳以其独特的优点,如简单的制备方法、优良的化学及热稳定性、良好的生物兼容性和无毒性等,受到越来越多的关注。石墨相氮化碳及其复合材料目前已被广泛应用于电催化、光催化、生物成像等领域。由于具有大的比表面积,同时又是富电子的疏水材料,石墨相氮化碳相关材料被认为是一种理想的样品前处理吸附剂。该文探讨了近年来石墨相氮化碳及其复合材料作为固相萃取、分散固相萃取、磁性固相萃取、固相微萃取吸附剂在样品前处理中的应用,并对未来的发展趋势和应用前景进行了展望,以期为相关领域的研究提供帮助。As a new type of non-metallic material, graphite carbon nitride(g-C3N4) has attracted increasing attention due to its inherent advantages such as simple preparation, excellent thermal and chemical stability, as well as good biocompatibility and non-toxicity. Nowadays, g-C3N4 is widely used in electrocatalysis, photocatalysis, biological imaging, and so on. Because of its large specific surface area, π-electron-rich structure, and hydrophobic properties, g-C3N4 is considered an ideal candidate material for sample pretreatment. In this work, g-C3N4 and its composites as potential sorbents for solid-phase extraction, dispersive solid-phase extraction, magnetic solid-phase extraction, and solid-phase microextraction are reviewed, and the future trends and prospective are discussed.
