Characterization of Magnetic Carbon Nanotube–Cyclodextrin Composite and Its Adsorption of Dye
Bibliographic record
Abstract
β-Cyclodextrin (CD) grafted carbon nanotube (CNT) composites were prepared by the reduction of oxidized CNT with hydrazine hydrate in the presence of CD. The obtained reduced CNT-CD (RCNT-CD) was attached to iron oxide particles in preparation of magnetic RCNT-CD (M-RCNT-CD). These composites were characterized by Raman spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), and thermogravimetric analysis (TG). About 17 wt % CD was grafted onto RCNT, and about 23.5 wt % iron oxide particles were attached to the RCNT-CD. The kinetic adsorption fit the pseudo-second-order model, and the isotherm data followed the Langmuir model. The maximum adsorption capacity reached 196.5 mg/g for M-RCNT-CD, indicating that it is a good adsorbent for methylene blue. The positive free energy change (Δ G °) and negative enthalpy change (Δ H °) illustrated that the adsorption process was spontaneous and endothermic. M-RCNT-CD can be easily separated from solution in the magnetic field.

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.
