The demand for uranium stock has increased continuously in recent years due to the development of nuclear energy industry. The uranium resources on the earth mainly include the land mines and soluble uranium salts in the water system

such as the salt lakes and oceans. If the latter part of uranium could be properly extracted and utilized

the sustainability of nuclear energy industry can be remarkably enhanced. Additionally

suitable methods are necessarily developed to remove the hazardous uranium wastes and recycle the waste water produced by the nuclear plants. The solutions of both above issues are related to developing highly efficient uranium adsorption materials applicable in aqueous solutions. Amongst all adsorption materials reported so far

polymers attract great attention. As one of the most important types of materials

polymers materials have been tested in the real sea water and shown promising results. With the increasing research efforts invested into the field

polymers with high uranium adsorption capacity and selectivity as well as optimal recyclability are likely to emerge soon and make feasible the utilization of nuclear resources in the natural water system.
