Abstract
With supporting electrolytes containing EDTA, KSCN, gelatine, and urotropine or acetic acid, Cu(II) ion forms a very sensitive incision in the dE/dt = f(E) curve, with which it is possible to detect as little as 0.01 . As many other ions do not show any activity in these media, the identification and determination of Cu(II) is possible in the presence of larger amounts of Pb, Sn, Zn, Cd, Sb, and other ions. Cu(II) can be determined in the range 0.2–8 with a maximum error of 4%. Any inactivity in these media is related to adsorption phenomena.
