“…In accordance with their results, the DLM median stability constants describe the pH-dependent explanation for these discrepancies, in accordance with prior studies of metal adsorption mechanisms [10,11,19,23], is the formation of outer-sphere complexes that could not be described by the DLM. Although previous studies differ in their perspective on the mechanisms of Cr adsorption onto hydrous ferric oxide and goethite, the adsorption behavior of Cr(VI) are generally well described using a combination of inner-and outer-sphere complexes [20,47,[50][51][52].…”
