Abstract
On the basis of theoretical considerations, a new catalytic reaction for the determination of nanomoler iron(III) concentrations has boon propesod, nomoly the oxidation of sulfanilic acid by potassium periodate using 1,10-phenanthroline as an activator. The optimum conditions for Fe(III) determination have been established as a result of kinetic studies. The reaction ensures a low detection limit (2×10−8 M), low coefficient of variation about 5% and high selectivity.Keywords
