Linear potential sweep in thin-layer cells

10 Linear potential sweep in thin-layer cells 

At a hydrodynamic electrode forced convection increases the transport of species to the electrode. However, the fraction of species converted is low. For example, for a ImM aqueous solution of volume 100 cm3 and a rotating disc of area 0.5 cm2 rotating at W = 4 Hz, the quantity electrolysed in 15 minutes is approximately 1 per cent. 

Thin-layer cells have been used with linear sweep, in coulometry and in chronopotentiometry. Here we limit the discussion to linear sweep— descriptions of this and other techniques can be found in Refs. 19-21. 

The fact that there is total electrolysis is one of the conditions in the solution of the equation for a reduction
