The invention discloses an application of a hydrogel bead material which is obtained by copolymerizing
acrylic acid and
acrylonitrile, performing amidoximation and then performing ionic crosslinking, and the hydrogel bead material is used for adsorbing
uranium in a high-
fluorine system. The material disclosed by the invention is an adsorption material which is low in cost, good in
chemical stability, easy to separate and capable of adsorbing
uranium in the high-
fluorine system, has an excellent
adsorption effect, can successfully realize separation of
uranium and
fluorine, reduces the radioactive content of fluorine
tailings, successfully realizes clean management and control and recycling of resources; The preparation method of the material is simple and convenient to operate, the production process is easy to control, and large-scale application can be achieved; after uranium adsorption, the material is automatically separated from the
system,
centrifugation and other operation are not needed, and
operability is high; the material is particularly suitable for treating uranium-containing
wastewater in a fluorine-containing environment in
nuclear industry enterprises in China; and uranium can be successfully and selectively separated from the fluorine-containing
wastewater through the material, and important
technical support is provided for solving the current nuclear potential safety
hazard problem.
