제목 Capturing, Removal, and Detection of Radioactive Cesium and Cobalt Ions from Contaminated Water Using PVA and PMAA Macrocomplex with Encapsulated Dye in Alginate Bead
초록 Radioactive isotopes are the products of uranium fission, and can be easily dissolved in water during an accident at a nuclear reactor, such as those that occurred at Chernobyl in 1986, and at Fukushima, Japan in 2011. Leaks of radioactive materials such as 137Cs isotopes also occurred during minor accidents at nuclear power stations. The wide use of radioisotopes requires effective methods to manage radioactive waste, and methods currently used are complex and extremely costly. Herein we demonstrate a potentially cost-effective method to remediate 137Cs+ and 60Co2+ ions from contaminated water using the unique chemistry of PVA, PMAA and alginate bead, which can efficiently trap them for safe disposal. In the present study, we show how PVA, PMAA, and alginate bead can be used to efficiently remove radioactive 137Cs+ and 60Co2+ ions from aqueous solution by cation exchange.
