In order to treat simply and safely the waste-containing radioactive technetium, a study of the removal of pertechnetate ion (the main chemical form of technetium) from radioactive waste was carried out using an anion-exchange membrane in which trimethylhydroxylpropylammonium groups were homoge-neously dispersed with high density. flux through the paper membrane is larger than that through a polymer membrane; moreover, in the paper membrane can exist in the membrane phase in spite of the presence of a large amount of Cl-. The anion-exchange paper membrane possesses three outstanding characteristics: (1) higher fluxes of and Cl- than that of the polymer membrane, (2) almost the same occupation of in available ion-exchange sites as in the polymer membrane, and (3) higher diffusional membrane permeability ratio than that of the polymer membrane.
