Abstract
The kinetics of zinc electrodeposition on steel from alkaline tartrate bath was studied as a function of
tartrate, sodium hydroxide and zinc ion concentrations. The rate of build up of the zinc deposition was
found to obey the equation v = rate of build up = k (Zn2+{6 (OU-{S (tartrate)1.5. Additions of
furfuraldehyde to the bath inhibited the rate of build up and the inhibition was due to adsorption of
furfuraldehyde molecules on the growth sites of the zinc nucleus and controlled its growth. This inhibition
decreased with current density. The hydrogen evolution reaction was favoured by furfuraldehyde.
