Speciation of Chromium Metal Ions by RP-HPLC [PDF]

open access: yesJournal of Chromatographic Science, 2009
A high-performance liquid chromatographic method with UV detection, based on chelation with morpholine-4-carbodithioate (MDTC), has been developed for the speciation of chromium. Simultaneous preconcentration of Cr(III) and Cr(VI) in aqueous solutions was achieved by extraction of metal species in chloroform as MDTC complexes.
