Potentiality of Graphene Oxide and Polyoxometalate as Radionuclides Adsorbent to Restore the Environment after Fukushima Disaster: A Mini Review

This paper discusses the promising candidate of excellent materials, graphene oxide (GO) and polyoxometalates (POMs), for radionuclide adsorbent. In this perspective, unique properties GO POMs make them ideal candidates developing new composites having ability to adsorb radionuclides, several essential things are reviewed. First, anchoring mechanism deposit POM on surface area by (i) carboxylation method, (ii) covalent bonding, (iii) impregnation method. Second, radionuclides removal is described in systems: coagulation, electrostatic interaction, ion trapping, (iv) H+-exchange. Third, experimental condition that employed enlarge sorption capacity such as pH adjustment, employing multiple oxidations, cation charge. A thorough understanding POM-anchored material can pave way future research similar materials. It also help nature interactive collaboration present between POM.
