ABSTRACT:
A spherical ion exchange resin composed of a phenolic resin and a metal hydroxide is disclosed. The metal hydroxide is enclosed and bound with the phenolic resin. A method for producing such an ion exchange resin and a method for selectively adsorbing ions using the same is also disclosed. The ion exchange resin is capable of efficiently recovering ions contained or dissolved in water in trace amounts and, hence, can be applied to any aqueous solution containing ions. For example, it can be used to recover useful substances from sea water and to purify waste waters from nonferrous refineries and nuclear power plants.
