ADSORPTION OF REACTIVE DYE BY A NOVEL ACTIVATED CARBON PREPARED FROM THEVETIA PERUVIANA
Bibliographic record
Abstract
This investigation was to evaluate the adsorption capability of activated carbon prepared from Thevetia Peruviana wood for removal of reactivetextile dye (RO4) from aqueous solution. Batch adsorption experiments were performed as a function of initial dye concentration, contact time,temperature and pH. The amount of dye adsorbed increased while increasing the initial concentration and temperature of the solution. Theexperimental data fitted well to Pseudo second order kinetic model with Intra particle diffusion as the rate determining step. Adsorption data fittedwith Langmuir model. The negative value of Gibb’s free energy (∆G°) indicated that the adsorption was spontaneous in nature. The results showedthat the activated carbon of Thevetia Peruviana was suitable for the removal of the reactive dyes from the aqueous solutions. The positive value ofenthalpy (∆H° ) indicated that the adsorption of the selected dyes were endothermic.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
