Degradation of atrazine with titanium dioxide immobilised in compact recycled glass
Bibliographic record
Abstract
This research studied the feasibility of a porous glass/titanium dioxide (TiO 2 ) composite for the photocatalytic degradation of atrazine under ultraviolet (UV) irradiation. The composite was obtained by immobilising titanium dioxide nanoparticles (in anatase form) over a sintered glass substrate through physical processes requiring high-temperature post-treatments for effective attachment. The initial deposition of the nanoparticles was attained by gravitational decanting from titanium dioxide suspensions evaluated in two different solvents: ethanol and acetic acid. The highest amount of titanium dioxide immobilised over the glass substrate occurred at 900°C for 2 h with no polymorphic structural change in the nanoparticles as confirmed by X-ray diffraction analysis. Treatability studies of atrazine solutions demonstrated a 95% reduction in atrazine levels after being in contact with the glass/titanium dioxide composite under UV light for 6 h. Also, the experimental results demonstrate possible exhaustion of the glass/titanium dioxide composite after 36 h of continuous treatment.

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.
