抄録

A novel flow-injection (FI) photometric method has been proposed for the successive determination of iron(III) and copper(II). It is based on the effect of activators such as 1,10-phenanthroline and 2,9-dimethyl-1,10-phenanthroline (neocuproine) on iron- and copper-catalyzed oxidative coupling of p-anisidine with N,N-dimethylaniline in the presence of hydrogen peroxide. By injecting two activators, alternatively, into the FI system, iron(III) (50–200 ng cm⁻³) and copper(II) (5–20 ng cm⁻³) can be selectively determined.
