Abstract
Abstract A comparative evaluation is presented of physical and chemical treatments performed on coconut shell powder, in relation to the adsorption capacity of Cu 2+ /Cd 2+ ions. The chemical treatment consisted of impregnation with monoethanolamine (mass ratio of 1:1) or a microemulsion (composed of 10 wt % sodium octanoate). The physical treatment was through steam explosion ( P = 5 bar, T = 210 °C). Treatment efficiency was assessed using physical characterization of the adsorber material. Assessment of the ion adsorption capacity was performed in batch mode. The comparative investigation was carried out based on the Langmuir model constants, kinetic constants, and thermodynamic parameters. The efficiency of the modifications was also evaluated through adsorption‐desorption cycles.

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
