Summary:Studying the adsorption behavior of Yangjiang granite to Sr2+ is very meaningful for the safety assessment of the low- and medium-level nuclear waste repository in Yangjiang. In this study, experimental samples were obtained from the granite rock formations near the low- and medium-level nuclear waste repository in Yangjiang. The static adsorption experiment was performed study the adsorption behavior of Yangjiang surrounding rocks granite on Sr2+. And the effect of contact time, initial concentration, reaction temperature, pH, as well as cation and anion on the adsorption behavior of granite was studied in detail. The physical and chemical compositions of Yangjiang granite were investigated by X-ray diffraction spectra(XRD), X-ray fluorescence spectrometer(XRF), scanning electron microscopy-energy dispersive spectroscopy(SEM-EDS), Fourier transform infrared spectra(FTIR) and Zeta potential analyzer. The characterization studies show the granite surface becomes rough after adsorption. The results of static ad
