Metal oxides/SiO2/zeolite (MSZ) is being developed to treat radioactive wastewater at the Fukushima
Daiichi Nuclear Power Plant. XRD and Raman spectroscopy showed Fe3O4 was not damaged while MSZ synthesis. Its adsorption capacity was almost same as plain zeolite, suggesting most of zeolite is present on the surface of MSZ.
