Each is checked against this paper’s own text: does it say what the citing paper says it does?
When equimolar amounts of Pb, Cr, and Cu were added together, the surfaces of ferrihydrite and the organo-mineral complex were covered >50% (53-56%) by Pb, 32-36% by Cr, and 9-13% by Cu.
“When equimolar amounts of each metal were added, the surfaces of ferrihydrite and the organo-mineral complex were covered >50 % (53 -56 %) by Pb, 32 -36 % by Cr, and 9 -13 % by Cu.”

In the presence of large amounts of Pb and Cr, some sites were still occupied by Cu even though Cu had a much lower affinity than the other two metals for both sorbents.

A small proportion of the sites on both ferrihydrite and the organo-mineral complex had a high affinity for Cu, particularly on the organo-mineral complex.
“Evidently, a small proportion of the sites on both sorbents had a high affinity for Cu, particularly on the organo-mineral complex.”

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.
