Abstract
The effects of sodium lauryl sulphate(SLS) in the presence and absence of antimony(III) on the current efficiency, power consumption and pol arization behaviour of zinc were determined. The surface morphologies and deposit crystallographic orientations were also evaluated. The res ults were compared with glue as the addition agent. The addition of so dium lauryl sulfate to the zinc sulfate solution increased current eff iciency, reduced power consumption and improved the surface morphology . Maximum current efficiency and minimum power consumption were achiev ed on addition of 0.02 mg dm(-3) Sb with 1 mg dm(-3) sodium lauryl sul fate.
