Application of ‘treating the waste with waste’: Fabrication of hierarchically hollow structures of <scp>AlOOH</scp> / <scp> Al <sub>2</sub> O <sub>3</sub> </scp> as adsorbents for the high efficiency removal of methyl blue
Bibliographic record
Abstract
Abstract Hierarchically hollow structures of AlOOH and Al 2 O 3 were hydrothermally fabricated employing Al 2 (SO 4 ) 3 obtained from the aluminium residue in zinc hydrometallurgy, which exhibited the excellent removal capacities and rates for methyl blue. The unique hollow spherical structures composed of numerous nanosheets offer the high specific surface areas. the adsorption begins, equilibrium can be reached within 10 min. The maximum adsorption capacities are 224.85 and 415.53 mg · g −1 on hollow structures of AlOOH and Al 2 O 3 , respectively. The adsorption conforms to the pseudo‐second‐order model and can be described by the Redlich–Peterson model. In addition, the two hollow spherical structures have good regeneration performance. Hollow spherical structures have the advantages of low cost, simple synthesis, fast adsorption rates, and large capacities, and are the qualified alternatives for the dyes removal.

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.
