Kinetic and Thermodynamic Studies on the Adsorption of Zn2+ onto Chitosan-aluminium Oxide Composite Material
Bibliographic record
Abstract
This study presents kinetic and thermodynamic studies on the adsorption of Zn2+ onto chitosan-aluminium oxidecomposite material. The adsorption of Zn2+ onto chitosan-aluminium oxide composite material was found to followpseudo-second-order kinetic model and the apparent adsorption activation energy (Ea) was measured to be37.20kJ/mol. Adsorption was mainly chemical adsorption. Thermodynamic data supported Langmuir adsorptionmodel and the enthalpy of adsorption (ΔHθ) and the entropy of adsorption (ΔSθ) were found to be 17.81kJ/mol and109.77J/(mol?K), respectively. The adsorption Gibbs free energy (ΔGθ) decreased with the increase of temperature.

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.
