Abstract
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
