Abstract

fetched live from OpenAlex

Dyes are one of the most common pollutants in wastewater due to their widespread use. Therefore, to protect aquatic ecosystems, dyes must be treated in situ and/or in vivo. In this study, poly(glycidyl methacrylate) (PGMA) gels were synthesized. PGMA gels were subsequently modified with diethylenetriamine (DETA) and tetraethylenepentamine (TEPA) containing different numbers and lengths of amino groups to obtain PGMA–NH 2 hydrogels. Finally, these hydrogels were used for the adsorption of Congo red (CR). Adsorption studies were carried out according to the batch adsorption procedure. From the study, the contact time was found to be 40 min and the highest adsorption capacities of 196 and 147 mg/g for PGMA–DETA and PGMA–TEPA were reached, respectively. Isotherm and kinetic experiments showed that the adsorption obeys the Freundlich isotherm and pseudo-second-order equation. The CR dye is an anionic indicator dye. These results showed that PGMA–NH 2 hydrogels have significant potential for efficient adsorption of anionic dyes.

Teacher imitation

Not 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.
