N2 - Results for the measurement of the diffusion coefficients of Tl in a Tl/Hg amalgam (D), and Tl in 1.0 M KF aqueous solution (D) are presented. The values of D = (1.2 ± 0.1) × 10 cm s and D = (2.4 ± 0.2) × 10 cm s at 22 ± 1 °C are obtained by means of comparison of experimental deposition and stripping chronoamperometric transients with theoretical simulations for a 12.5 μm radius hemispherical mercury drop in which Tl is first deposited and then stripped.
