  • ...In the present study, we fully optimize the use of ITD based Cr speciation with DPC-based measurement, with special attention to matrix isolation and interference in Cr(VI) measurements by metal cations [25-28] and anions [29,30]....

TL;DR: The mechanism of the classical color reaction between chromate and carbazide has been studied in solution from various physico-chcmical points of view as discussed by the authors, which leads to the conclusion that tlie chromate-carbazidc reaction is a composite one involving preliminary oxidation followed subsequently by complex formation.
