In recent years, the pollution of radionuclides to water is becoming more and more serious with the rapid development of nuclear technology. The expansion of activities, such as uranium mining, nuclear research, weapon manufacturing,and nuclear power generation will produce many radioactive isotopes. Among these radionuclides, uranium (VI) (U(VI)) poses a great threat to the biosphere due to the enhanced chemical affinity with organic ligands, radioactive toxicity and long half-life.Therefore, it is necessary to develop a technology to reduce or recover U(VI) in wastewater for decreasing the risk of U(VI) pollution to the environment and realizing the resource utilization of U(VI). The adsorption method has been widely studied due to the relatively mature technology, good repeatability of adsorbent, high adsorption efficiency, low cost and easy operation. Titanium dioxide (TiO2) is considered one of the best adsorbents due to the low cost, non toxicity and high chemical activity. However, the agglomeration of TiO2 particles will reduce the number of active sites per unit area, leading to a weakened adsorption ability for U(VI). An effective strategy to improve the adsorption ability is to prevent the aggregation of TiO2 particles and improve the surface activity of TiO2. Therefore, in this work, iron doped nano-TiO2 materials (Ti–Fe composites) were prepared by the sol gel method,aiming to prevent the aggregation of TiO2 particles in use and improve the adsorption performance.
