Abstract
AbstractPollution in nuclear industry is a difficult problem to solve. To solve this problem, we synthesized the NH2‐MIL‐125 modified materials (MIL‐125‐P@TiO2) by hydrothermal synthesis and also investigated the adsorption properties of uranyl ions. To improve the adsorbability of materials, we loaded titanium dioxide and phosphorylate it. The materials were characterized by means of XRD, SEM, infrared, thermogravimetric and XPS. The adsorption properties of uranyl ions on the two materials were studied by batch adsorption experiments. The results showed that the maximum adsorption capacity of modified material is 333.62 mg/g and 614.82 mg/g at 25 degrees Celsius by fitting the Langmuir model respectively, and the modified material has a better adsorption ability at 25 degrees Celsius with initial uranium concentration at 100 mg/L.
