Abstract
Abstract Chemically durable and effective absorbent materials for selenite (SeO 3 2− ) remain highly desirable for contamination remediation. Now a bismuth‐based metal–organic framework (Bi‐MOF, CAU‐17) was used as adsorbent to capture SeO 3 2− anions from aqueous solution with ultrahigh adsorption capacity of 255.3 mg g −1 and fast kinetics. Furthermore, the adsorbent showed excellent selectivity for SeO 3 2− and was able to work steadily in a broad pH range of 4–11. Density functional theory (DFT) calculation, XANES modeling, and EXAFS fitting suggested that SeO 3 2− anions were immobilized by forming Bi−O−Se bonds (T‐3 structural model) though splitting the O−Bi−O bond in the crystal structure, leading to a structural transformation of CAU‐17 in the solid state.

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
