A flow injection method intended for the determination of cerium based on its catalytic effect
on the oxidation of gallocyanine by peroxydisulfate in acidic media is described. The
proposed flow injection manifold incorporates a ion exchange separation system in the
carrier stream. The decolorization of gallocyanine due to its oxidation was used to monitor
the reaction by spectrophotometry at 524 nm, The variables which affected the reaction rate
were fully investigated. By this method, Ce (IV) can be determined in the range 0.30-10.0 ...
