Abstract
In this study, modified zeolites were prepared through the modification of raw zeolites, using hydrochloric acid (HCl) and cetyl trimethyl ammonium bromide (CTAB), whose properties were then characterized by a Zeta Potential Meter and an X-ray diffractometer. Also, the adsorption mechanisms were investigated in depth. The experimental results indicated that, in terms of the adsorption capacity of Rhodamine B in water, the modified zeolites were more favorable than the raw zeolites. As the dosage of adsorbent increased, the removal percentage of Rhodamine B in the water increased, while the unit adsorption capacity decreased. The pH value of the solution, and reaction temperature imposed little effects on the adsorption of the Rhodamine B. In accordance with the adsorption thermodynamic results, Langmuir and Freundlich isothermal adsorption models were able to accurately describe the adsorption of Rhodamine B in water by the modified zeolites. The fitting results had a higher correlation when using a Freundlich isothermal model. At 303 K, the static saturated adsorption capacity was 4.41 mg/g. The kinetic results demonstrated that the adsorption of Rhodamine B in water using modified zeolites fit well with the pseudo-second-order kinetic model.

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
