Phosphorus adsorption and desorption properties of three synthetic iron oxides and their relation to phosphorus adsorption saturation
Bibliographic record
Abstract
The differences of P adsorption-desorption characteristics of amorphous and crystalline iron oxides and their(relation) to P adsorption saturation were studied by using three synthetic iron oxides.The results showed that P adsorption properties of these three synthetic iron oxides could be described by Langumir equation with a correlation coefficient larger than 0.9 being statistical significant at 1% level.It was found by comprehensively taking Q_m(maximum quantity of adsorption),K(adsorption constant) and MBC(maximum buffing capacity) into account,ferrihydrate(amorphous) was much larger than crystalline iron oxides(goethite and hematite) in both intensity and capacity of P adsorption.P adsorbed by ferrihydrate was much more difficult to be desorbed than those by goethite and hematite.The large active surfaces of ferrihydrate contribute little on P desorption.It was suggested by our results that P adsorption saturation might be a promising integrated index for estimating the intensity and capacity of P adsorption-desorption in soils or iron oxides.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
