Abstract
The safety of drinking water is vital for human health. In recent years, organic micropollutants (OMPs) in water have attracted much attention because they are toxic, non-degradable, easily migratable and have wide sources. Since 2017, inspired by the pioneering work on the adsorption removal of OMPs from water by porous polymerized β-cyclodextrins, the adsorption of OMPs in water by macrocycle-crosslinked polymers (MCPs) has received widespread attention. Classical macrocyclic hosts such as cyclodextrin, calixarene, pillararene and other emerging macrocycles have been employed for this purpose. This review encompasses the advancements on the removal of OMPs from water by MCPs, involving the building blocks of polymers, types of OMPs, the preparation and performance of each MCP. An overview of challenges and future research directions in this regard are also discussed.
