In the decommissioning process at TEPCO Fukushima Daiichi Nuclear Power Plant, it is expected that contaminated water that may have been contaminated with uranium is found. Graphene oxide is a material that adsorbs uranium very efficiently. By using this material to extract uranium from contaminated water, it is possible to analyze uranium with high sensitivity. In this study, we developed a method for extracting uranium from simulated contaminated water with graphene oxide and quantifying uranium by total reflection X-ray fluorescence spectrometry.
