以4′-氨基苯-18-冠-6 （AB18C6）和Fe3O4-CHO为原料，通过Mannich反应合成了一种新型的Pb2+磁性吸附剂。该方法对Pb2+具有良好的吸附和选择性，在苹果、牛奶和大米中痕量Pb2+的选择性测定中具有良好的应用前景。
A novel magnetic adsorbent for Pb2+ was synthesized based on 4′-aminobenzo-18-crown-6 (AB18C6) and Fe3O4–CHO via the Mannich reaction. It showed excellent adsorption and selectivity for Pb2+, and the established MSPE method had excellent potential, displaying the selective determination of trace Pb2+ from apples, milk and rice.
