Abstract
In the present work, graphite nanostructures are prepared by thermolysis of a prepared polyacrylamide gel. The gel was prepared by radical chain polymerization and the synthesis of the nanostructures was done by step annealing at different temperatures. The structural of the prepared materials was studied by X-ray diffraction (XRD). The presence of carboxylic and phenolic functional groups on the graphite surface was confirmed by FT-IR analysis. Batch adsorption experiments were conducted to study the effect of equilibration time, initial metal cation concentration, and solution pH for the removal of Cs(I) and Co(II) from aqueous solutions. Kinetic data of Cs(I) adsorption was found to be well fitted with a pseudo-first-order kinetic model. The obtained isotherm data were correlated with the Langumir and Freundlich isotherm models. The effect of temperature on the equilibrium distribution values was utilized to evaluate the change in the standard thermodynamic quantities of enthalpy (ΔH°), entropy (ΔS°), and Gibbs free energy (ΔG°).

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
