journal contribution
posted on 2023-06-23, 11:07 authored by Emily HilderEmily Hilder, Miroslav MackaMiroslav Macka, DP Bogan, Paul HaddadPaul HaddadA method was developed for the separation of CdII, PbII, PtII, CoII, NiII, BiIII, CrII, CuII and HgII bis(2-hydroxyethyl)dithiocarbamate (HEDTC) complexes by micellar electrokinetic capillary chromatography. The complexes were formed by pre-capillary reaction of the metal ions with an excess of the ligand and then separated using a 100 mM borate buffer (pH 9.2) containing 4% methanol (v/v), 10 mM sodium dodecyl sulfate and 0.1 mM HEDTC, with detection at 254 nm. All the metal complexes, except PtII and PbII, were baseline resolved and separation was achieved in under 7 min. Detection limits were in the range 22 to 133 ppb.
