Definitions

the invention is related to additives for zinc
cetylpyridinium-based additives cetylpyridinium-based additives .
additives generally organic compounds, which selectively increase the hydrogen evolution overpotential .
Cetylpyridinium chloride (CPC) a cetylpyridinium salt
the CPC additive had the most significant influence in the presence of antimony or antimony + glue combination, where it
electrowinning electrolyte (liquor) were connected to a power
the anodes and cathodes were made of lead and aluminium, respectively.
composition zinc sulfate 28 - 34% by weight, magnesium sulfate
CPC cetylpyridinium chloride
Table 1 Effect of CPC on the current efficiency of zinc electrowinning in the electrolyte containing 0.04 mg/1 Sb (as Sb-tartrate) .
Table 3 Effect of CPC on the current efficiency of zinc electrowinning in the electrolyte containing 0.04 mg/1 Sb (as Sb-tartrate) + 10 mg/1 glue.
the cell voltage is another important figure of merit of
Table 5 Effect of CPC on the average cell voltage in 4 hour experiments with 0.04 mg/1 Sb and 10 mg/1 glue in the electrolyte.
