Abstract
This study evaluates the effectiveness of three physico-chemical processes in treating acidic soil leachate. Chemical precipitation was tested using calcium hydroxide and sodium hydroxide, and electrocoagulation was evaluated via an electrolytic cell using mild steel electrodes, whereas sorption process was tested using cocoa shells as sorbent. Chemical precipitation was as effective as electrocoagulation in reducing both metals (Pb and Zn) under the permissive level (2.0 and 10 mg l –1 respectively), more than 97% of each metal was removed. By comparison, the sorption process using cocoa shells allowed reaching 90% of Pb removal, while the process removed 92% of Zn.

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
