Effect of temperature on the sorption and desorption of perfluorooctane sulfonate on humic acid
Open accessAbstract
Sorption and desorption of perfluorooctane sulfonate (PFOS) on humic acid at different temperatures were studied. It was found that the sorption process could be modeled with power kinetic equation very well, suggesting that diffusion predominated the sorption of PFOS on the humic acid. The sorption capacity was doubled when the temperature increased from 5 to 35 degrees C, and thermodynamics parameters deltaG0 was calculated to be -7.11 to -5.04 kJ/mol, AHo was 14.2 kJ/mol, and deltaS0 was 69.5 J/(mol x K), indicating that the sorption was a spontaneous, endothermic, and entropy driven process. Desorption hysteresis occurred at all studied temperatures which suggested that humic acid may be an important sink of PFOS in the environment.

The higher July φ values may be explained by enhanced adsorption capability due to the higher water temperature in July.
“This difference may be explained by the enhanced adsorption capability due to the higher water temperature in July (Jia et al., 2010).”

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.
