- Аннотация: Limited diffusion of the ferric hydroxide (ferrihydrite) nanoparticles in the polymeric network of the AG 50W����X2 sulfonated cation exchanger solvated with aqueous solutions of glycerol (70 and 90 wt.%) was studied in the temperature interval from 90 to 293 К. The Mössbauer spectra were obtained in three windows (250, 25, and 5 mm/s) because of large line broadenings observed in the experiment. The procedure of "seaming" of the time����dependent correlation functions <[∆x(t)]2> obtained by the Fourier transform analysis of the initial Mössbauer spectra made it possible to observe the behavior of the function in the extremely wide time range from 0.4 to 360 ns. The observed plateau of the function at long times is a direct proof of the limited nature of the motion. The experimental data were interpreted in the framework of physical models of limited diffusion. Key words: Mössbauer spectroscopy, Mössbauer probe, ferrihydrite nanoparticles, polymeric cation exchanger, Fourier transform, time dependent correlation function, limited diffusion.
