The influence of pH, co-existing ions, ionic strength, and temperature on the adsorption and reduction of hexavalent chromium by undissolved humic acid

Barnie, Samuel; Zhang, Jia; Wang, Hui; Yin, Huilin; Chen, Honghan (University of Cape Coast, 2018)

The retention of Cr(VI) in subsurface environment is highly dependent on humic acid (HA), however, the undissolved form is poorly investigated, the amount of which can be of two magnitude higher compared with the dissolved ...
Molecular structure-reactivity correlations of humic acid and humin fractions from a typical black soil for hexavalent chromium reduction

Zhang, Jia; Yin, Huilin; Wang, Hui; Xu, Lin; Barnie, Samuel; Chang, Jingjie; Liu, Fei; Chen, Honghan (University of Cape Coast, 2018)

Different soil humus fractions are structurally distinct from each other molecularly, however, the relationship between their microscopic molecular structures and the macroscopic reduction of Cr(VI) is still unknown, ...
Reduction mechanism of hexavalent chromium by functional groups of undissolved humic acid and humin fractions of typical black soil from Northeast China

Zhang, Jia; Yin, Huilin; Wang, Hui; Xu, Lin; Barnie, Samuel; Liu, Fei; Chen, Honghan (University of Cape Coast, 2018-04-05)

Soil organic which act as the main electron donors for Cr(VI) reduction; however, Cr(VI) reduction mechanism y different SOM fractions is still unclear, such as undissolved humic acid (HA) and humin (HM). In this study, ...
