Lazaro, Fernando published the artcileCatalytic-fluorometric determination of EDTA and iron(III) by flow injection analysis. Inhibition methods, Quality Control of 2215-33-0, the publication is Fresenius’ Zeitschrift fuer Analytische Chemie (1985), 321(5), 467-70, database is CAplus.
Methods are described for the direct determination of EDTA and indirect determination of Fe(III), based on the inhibition effect of EDTA on the catalytic action of Cu(II) on the oxidation of 2,2′-dipyridyl ketone hydrazone by H2O2 and on the decrease of this inhibition effect in the presence of Fe(III), resp. These methods allow the determination of EDTA in the ranges 0.4-2.0 and 0.2-1.0 μg.mL-1 for the normal and reversed flow-injection anal. (FIA) modes, resp., and 40-240 ng.mL-1 for Fe(III) by reversed FIA.
