Sonoelectrochemical oxidation of carbamazepine in waters: optimization using response surface methodology
Bibliographic record
Abstract
Abstract BACKGROUND The decomposition of carbamazepine ( CBZ ) in synthetic solution and in municipal effluent was investigated using a sono‐electrochemical reactor. Sono‐electrolysis was conducted using two concentrical electrodes installed in a cylindrical reactor containing a ceramic transducer. RESULTS CBZ concentration ( C 0 =10 mg L −1 ) optimally diminished up to 90% by applying a current intensity of 4.86 A for 177 min and by imposing an ultrasound power of 38.29 W. The optimal conditions were subsequently applied for tertiary treatment of municipal wastewater effluent contaminated with 10 µg CBZ L −1 . The reported removal efficiencies of CBZ , TOC , COD and colour were 93%, 60%, 93% and 86%, respectively. Likewise, the toxicity was completely removed (bacterium Vibrio fisheri ) from the municipal wastewater effluent (>96%). CONCLUSIONS The advantages of coupling ultrasonication and electrooxidation ( US‐EO ) treatment for CBZ removal were demonstrated. An experimental design methodology based on response surface methodology was applied to determine the optimal experimental conditions in terms of cost/effectiveness of removal. © 2014 Society of Chemical Industry

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.
