Abstract Ethylenediaminetetraacetic acid functionalized mesoporous silica (EDTA-SBA-15) was synthesized and used to efficiently remove corrosion products like Co(II), Ni(II), and Cu(II) generated in nuclear reactor coolants. The mesoporosity, long range order, and functional group loadings were confirmed by N2 adsorption/desorption, small angle x-ray scattering (SAXS), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR) techniques. The improved loading of EDTA on the SBA-15 surface significantly increased its adsorption capacity (1.33–1.44 mmol/g) for the above-mentioned corrosion products. Additionally, the fast equilibrium adsorption kinetics (
