Example :

Example:  V(V ) + e-  → V(IV).  If the solution contains a small amount of hydrogen peroxide V(V) is regenerated by oxidation of V (IV). 8 ×10-7 M V (V) in 0.1 M phosphate buffer at pH 4.9 gives a current that is few thousandths of microampere. But the similar concentration of V(V) in the presence of 0.007 M hydrogen peroxide gives 18.6 microamperes of current.

It is therefore, of importance for determining exceedingly low concentrations of original electroactive substance. Thus, the catalytic currents are highly meaningful for trace analysis of number of transition metal ions such as tungstate, vanadate, molybdate, titanium(IV), Te(IV) and Iron(III) with oxidizing agents like nitrate, hydrogen peroxide, chlorate, perchlorate, KIO3  and hydroxylamine because ic  is proportional to the concentration of electroactive substance (O).

The catal ytic currents are identified as Ic is independent of hcorr like kinetic currents.
