Аннотация
The limiting value of ion-exchange sorption capacity of the perfluorosulfonic membrane with respect to Tb3+ is reproducible when the cation is in excess in the solution. Modification of the membrane with azomethine bases is facilitated by the high diffusion mobility of the molecules and proceeds with the formation of strong surface compounds. The manifestation of coexisting emission centers in the Tb3+-modified membrane treated with azomethine is determined by the energy of the exciting light.
