Abstract

Pneuma toamperometry is applied to a new method for trace analysis of aqueous solutes in which the solute of interest is reacted to form a volatile electroactive product which is flushed from solution using an electroinactive gas. The gas stream passes over one surface of a hydrophobic gas-porous electrode, where the electroactive species is electrolyzed at constant potential, giving a current response proportional to the initial amount of the solute. Detection limits for the solutes tested are: Hg(II) (5 ppb), As(III) (3 ppb), (6.5 ppb), and I0³- (0.5 ppb).
