Abstract
Electrodeposition of various metals on platinum electrode in 0.1M oxalic acid with 0.4M potassium oxalate has been investigated. The deposition potentials of metals were +0.30 V (vs. S. C. E.) for Hg, -0.25 V for Cu, -0.30 V for Se, -0.50 V for Sb, -0.60 V for Pb, -0.75 V for Sn, -0.80 V for Cd and < -1.00 V for Fe, Ni, Co and Zn.
Among these, respective determination of Hg, Cu, Cd, Fe, and Zn at controlled potential was possible. Hg-Cu, Cu-Cd, Cd-Fe and Cd-Zn were separatorily determined.
