Abstract
The application of derivative spectrophotometry to the simultaneous determination of iron(III) and bismuth(III) with EDTA is described. The procedure developed does not require the solution of systems of equations and is suitable for concentrations of 0.5–8.0 µg ml–1 of iron(III) and 0.1–35.7 µg ml–1 of bismuth(III). The interferences, whether by anions or cations, are easily eliminated.Keywords
