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 <I>p</I>-anisidine with <I>N</I>,<I>N</I>-dimethylaniline in the presence of hydrogen peroxide. By injecting two activators, alternatively, into the FI system, iron(III) (50–200 ng cm<SUP>−3</SUP>) and copper(II) (5–20 ng cm<SUP>−3</SUP>) can be selectively determined.
