A novel magnesium silicate/diatomite sorbent (MSD) was fabricated using a facile hydrothermal method. The interaction mechanism of U(VI) on MSD was investigated by batch, spectroscopic and modeling techniques. The maximum adsorption capacity of MSD for U(VI) (31.54mg/g) is significantly higher than that of diatomite (12.74mg/g). XPS analysis indicated that the oxygen-containing groups (e.g., SiOH)...
