Abstract: Cu, Pb, Cd, and Zn as impurities in Be and Mg metals were detd. after accumulation on a hanging Hg-drop electrode in 1-2M HCl. The amts. were 10-6-10-8M in soln. or 10-4-10-6% by wt. in the metal. The same impurities in trace amts. in M HF were detd. directly by the oscillographic peak at higher concns. or after electrolysis as the accumulation on the electrode.
