Process for manufacturing phosphoric acid-type chelate resin as uranyl ion absorbents |
摘要 |
This invention relates to a process of manufacturing phosphoric acid-type chelate resins as uranyl ion adsorbents having enhanced chelation and re-utilizing ability by introducing plenty of phosphoric acid groups both on main- and side-chain of the copolymer skeleton. The resin is prepared by both the radical suspension copolymerization of vinyl monomers such as styrene, divinylbenzene, and bis-(2-chloroethyl) vinylphosphonate and the additional introduction of phosphono group onto the copolymer. |
