Abstract
Abstract Liquid-liquid extraction of platinum group metals Rh(III), Pt(IV), and Pd(II) was carried out from aqueous chloride media with Cyanex 925 in the absence and presence of tin (II) chloride. In the absence of tin (II) chloride, the order of extraction was found to be Pd > Pt > Rh. However, in the presence of tin (II) chloride, it changed to Pt > Rh and is negligible in the case of palladium. The extraction of rhodium was studied under the influence of variables such as hydrochloric acid, reagent, and tin (II) chloride concentrations; equilibration time; and effect of diverse ions. The separation of Rhodium (III) from Pt(IV) and Pd(II) was enabled because of differences in their extraction and stripping abilities when Cyanex 925 is used.

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 it
