ABSTRACT:
An inorganic ion-exchanger supported on a carrier suitable for recovery of useful resources in sea water, removal of impurities from high temperature boiler water in nuclear reactors or industrial boilers, removal of impurities in industrial waste water, etc. is prepared by supporting an active component of inorganic ion exchanger, such as hydrous oxide of metal, for example, titanium, zirconium, etc. on a porous carrier such as alumina, silica, or activated carbon, where a pH of a solution in contact with the active component and the carrier is adjusted so that the active component and the carrier can have zeta potentials of opposite polarities to each other, and an inorganic ion-exchanger having a larger amount of the supported active component and firmly supporting less bleedable active component can be obtained by setting out a supporting condition on the basis of the polarity of zeta potential.
