EXAMPLES

Example 3-1 Voltammogram (a) was obtained for adsorptive stripping measure-
ments of Fe(III) in sea water. Voltammograms (b) and (c) show successive standard
additions of 4 ppb Fe(III). Find the concentration of Fe(III) in the sample.

Solution The resulting current peaks lead to the following standards additions plot:
