Degree of activation, specific surface area and surface chemistry fonction of activated carbons from Acacia auriculaeformis and Acacia mangium
Bibliographic record
Abstract
Three physico-chemical characteristics of Acacia activated charcoals were determined: the degree of activation, the specific surface and surface functions. The coals are prepared from Acacia auriculaeformis and Acacia mangium, leguminous and fast growing trees, available in Cote d’Ivoire. They were activated by chemical means, by impregnation with phosphoric acid (H3PO4). Analysis of the results indicates that the activation yields are below 50% for both types of coal. In addition, the activated carbon-based Acacia auriculaeformis has a larger surface area than that based Acacia mangium. The two activated coals have mixed surface functions, predominantly acid, which give them a dual reactivity for both anionic and cationic adsorbates.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
