Yx. Xu et al., DETERMINATION OF THE DIFFUSION-COEFFICIEN T OF LA IN HG BY CHRONOAMPEROMETRY, Gaodeng xuexiao huaxue xuebao, 17(11), 1996, pp. 1711-1713
Two methods were used to prepare La amalgam. One was displacing La3+ i
on with Na amalgam, the other was mercuty cathode electrolytic method.
The diffusion coefficient D of La in Hg was determined by chronoamper
ometry in NaAc-HCl-NaSO4 pH=6 supporting electrode to be (4.90+/-0.11)
x 10(-6) cm(2)/s at 25 degrees C
