The data presented in Table 6 also indicate that the alloy
Zn + 0.01 wt.% Mg + 0.01 wt.% Pb has anode efficiency values
of 98.7 and 93.3% at a current density of 120 mA/cm 2,
and 98 and 96.6% at a current density of 25 mA/cm = in the
electrolytes C and D, respectively. It is therefore concluded
that the alloy can be used safely as an anode between 25 and
120 mA/cm 2 in the above two electrolytes (C and D), with
anode efficiency values that vary between 93 and 98%.
