The selectivity sequence of Pb, Cu, and Cd sorbed by an Ultisol (as well as by goethite) was Pb > Cu > Cd at pH 4.2 but changed to Cu > Pb > Cd at pH 5.3.
“In fact, this author found that the selectivity sequence of Pb, Cu, and Cd sorbed by an Ultisol (as well as by goethite) was Pb > Cu > Cd at pH 4.2 but it changed to be Cu > Pb > Cd at pH 5.3.”

At low pH, both Pb and Cu were sorbed mainly through the formation of surface complexes and consequently Pb showed a greater capacity to form surface complexes on variable charge.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
