Abstract
ABSTRACT The adsorption characteristics of phenol, 2,4,6-trichlorophenol (2,4,6-TCP) and atrazine onto humic acid–carbon hybrid materials were investigated under different experimental conditions (ionic strength, pH, adsorbent dose, agitation time and initial concentration). It was found that ionic strength has insignificant effect on the adsorption process which peaked at acidic pH. The kinetic data were fitted to Elovich equation and intra-particle diffusion models. Kinetics results showed that the adsorption can be represented by two steps: a rapid step dominating the first 5 min followed by a slower uptake to the final steady-state value. On the other hand, equilibrium data were examined by Freundlich and Langmuir equations. Langmuir was the best model fit for the adsorption of 2,4,6- TCP onto the studied materials, phenol adsorption on carbon-coated insolubilized humic acid and atrazine adsorption onto insolubilized humic acid and carbon-coated insolubilized humic acid. The study proved that humic acid–carbon hybrid material has higher adsorption capacity than the pure materials.

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
