      abstract     = {The interaction between hexavalent chromium Cr(VI), as
                      K(2)CrO(4), and standard humic acids (HAs) in bulk solution
                      was studied using three complementary analytical methods:
                      UV-Visible spectroscopy, X-ray absorption spectroscopy and
                      differential pulse stripping voltammetry. The observed
                      UV-Vis and X-ray absorption spectra showed that, under our
                      experimental conditions, HAs did not induce reduction of
                      Cr(VI) to its trivalent chemical form. The interaction
                      between Cr(VI) and HAs has rather led to the formation of
                      Cr(VI)-HAs micelles via supramolecular chemical processes.
                      The reported results could contribute towards explaining the
                      relative persistence of ecotoxic hexavalent chromium in
                      soils.},
