This approach was adopted by ICI in a technology developed for their two
compartment FM21 electrolyser [22,23]. The anolyte was continually saturated
with sodium sulfate so that the ft formed at the anode was largely trapped as
bisulfate in ...

Figure 5.11 Comparison of the current efficiency for the formation of H2SO4 from
the splitting of sodium sulfate in a two compartment cell (a) without and (b) with
continuous saturation of the anolyte with sodium sulfate. j = 3 kA m~2.

It should be noted, however, that the actual current efficiencies that are measured
will not depend on the acid strength alone but also on the concentration of the
sodium sulfate solution and the current density that is used. One of the ...
