Abstract
Cocoa shells, a by-product of the food industry, is a promising adsorbent for the treatment of acid metal loaded wastewaters, particularly for lead removal. Elution tests carried out using different concentrations of hydrochloric acid have shown that a good portion can be eluted using a short contact time (approximately 10 min) and a diluted acid solution (0.51.0 M). The use of a more concentrated acid solution causes significant mineralization of the adsorbent and does not allow to improve the elution yield. Repeated adsorptionelution cycles have shown that cocoa shells can be reused for many times. However, their lead adsorption capacity progressively decreases from 19.3 mg Pb/g during the 1st cycle to 4.8 mg Pb/g during the 10th cycle. Finally, the use of successive adsorptionelution cycles is only interesting, from an economical point of view, in the case where the acid solution is used for many elution steps. Key words: adsorption, elution, lead, cocoa shells, effluent, acid.

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
