Chemical modification of biochar using strong acids such as HCl, H2SO4, HNO3, and H3PO4 can alter the porous surface structure and increase the density of free carboxyl and hydroxyl groups, thereby enhancing adsorption capacity.
“Chemical modification of biochar using strong acids like HCl, H2SO4, HNO3, and H3PO4 can alter the porous structure of the surface and increase the density of free carboxyl and hydroxyl groups, thereby enhancing its adsorption capacity [19-21].”

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.
