Determination of trace impurities in cadmium compounds by flame atomic absorption spectrometry after solid phase extraction
Bibliographic record
Abstract
Un systeme de separation/preconcentration fut developpe pour la determination d'impuretes de Cu (II), Fe(III) et Pb(II) dans des sels de cadmium par spectrometrie d'absorption atomique a flamme (FAAS). La procedure est basee sur l'adsorption des analytes sur une resine d'Amberlite XAD-1180 enrobee de Chromotrope 2R. L'effet de quelques parametres analytiques, incluant le pH de la solution de l'echantillon, le volume d'echantillon, les effets de matrice du cadmium, et les debits des solutions d'echantillons et d'eluant, fut explore. Dans des conditions optimales, la deviation standard relative de la methode combinee de traitement de l'echantillon, preconcentration et determination par FAAS (n=7) est en general inferieure a 10%. La limite de detection (3a) se situe entre 0.024-0.20 mg/l, La methode fut appliquee a la separation et preconcentration de trois elements trace dans des solutions de sels de cadmium.

How this classification was reachedexpand
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.
