Based on the equation solved and experimental data, the diffusion coefficients corresponding to the exchange process $$\bar H^ + --Li^ + $$ (OAc−) and Li+−H+ (OAc−) at 17°C are found to be 7.7×10−9 and 6.2×10−8 cm2 s−1 and the activation energies 3.4×104 and 5.0×103 J mol−1, respectively. Compared to the gel type of styrene-divinylbenzene strong acid exchanger with 20% cross linking, it can be concluded that the rate of $$\bar H^ + --Li^ + $$ or $$\overline {Li} ^ + --H^ + $$ exchange is 3.5 times faster than that in the organic exchanger.
