Abstract

The effects of sodium lauryl sulphate(SLS) in the presence and absence of antimony(III) on the current efficiency, power consumption and polarization behaviour of zinc were determined. The surface morphologies and deposit crystallographic orientations were also evaluated. The results were compared with glue as the addition agent. The addition of sodium lauryl sulfate to the zinc sulfate solution increased current efficiency, reduced power consumption and improved the surface morphology. Maximum current efficiency and minimum power consumption were achieved on addition of 0.02 mg dm-3 Sb with 1 mg dm-3 sodium lauryl sulfate.
