Abstract
The current study deals with the removal of mercury ions from aqueous solutions by sulfurized and original activated carbons (ACs) in the batch and fixed bed modes. The modified sample containing sulfur groups showed higher uptake capacities and larger breakpoints. The XPS and EDS analyses confirmed the introduction of carbon–sulfur bonds onto the AC’s surface after impregnation with dimethyl-disulfide. In the work, the diffusional models named, “Film Pore Concentration-Dependent Surface Diffusion (FPCDSD)” and “Axial dispersion Film Pore Concentration-Dependent Surface Diffusion (AFPCDSD)” were respectively applied to explain the batch and bed-mode kinetic data to clarify the rate-controlling mechanisms and estimate the diffusional/mass transfer properties of adsorbate–adsorbent systems. In all cases, the sulfurized AC showed greater Ds (surface diffusivity) values attributed to the higher mercury loading on this sorbent which facilitates ion hopping on the surface sites. The internal and film diffusions both played notable roles in mercury adsorption mechanism.

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
