摘要：

The Fourier-transform NMR pulsed field gradient spin-echo method was applied to the measurement of the self-diffusion coefficients of the active components in the commercial extractants LIX65N, LIX63 and Cyanex 272. CCl//4 and CDCl//3 were used as solvents. The self-diffusion coefficients in 0. 16 M CDCl//3 solutions are 8. 2, 9. 2 and 6. 7 multiplied by 10** minus **1**0 m**2 s** minus **1, respectively.
