Covalent organic frameworks (COF) materials for selective radionuclides removal from water

The efficient and safety elimination of radioactive nuclides from complicated systems is crucial to both the healthy and fast development of nuclear energy, and the protection of environment and human health. Covalent organic framework (COF) materials have studied extensively in multidisciplinary research areas attributed to their outstanding physicochemical properties. This review summarized the recent works for the removal of radionuclides by COFs through the strategies of sorption, reduction, chemical precipitations, and discussed the reaction mechanisms from batch/column results, theoretical calculation and spectroscopy analysis. The challenge was given in the end.
