Decolorization and destruction of metallophthalocyanines in aqueous medium by ultrasound: a feasibility study
Bibliographic record
Abstract
Most currently available treatment methods for the phthalocyanine type of pigments have shortcomings and problems. An alternative approach using chemical-assisted ultrasound was conducted and the feasibility for the decolorization and destruction of the metallophthalocyanines has been demonstrated. Both copper and nickel phathlocyanine, with water and organic solvents at ambient temperature and atmospheric pressure in the presence of catalytic amount of oxidant under 20 kHz of frequency at a power level of 3759 W/cm 2 , can reach a destructive level of 9295% within 50 min. Preliminary kinetic studies found that the process belongs to the Langmuir-Hinshelwood type. The reaction mechanism is similar to that of metalloporphyrins, and the intermediate is an unstable ion radical that can release metal. Key words: metallophthalocyanines, ultrasound, decolorization, destruction, demetallation, dyebath wastes.

How this classification was reachedexpand
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.
