Degradation of pharmaceutical contaminants in water by an advanced plasma treatment
Bibliographic record
Abstract
ABSTRACT Contamination of water bodies with pharmaceutical compounds and their adverse effects on human and wildlife has been a source of concern for many societies. The need for more effective water treatment processes has been felt to eliminate these contaminants from water. In this work, single electrode non-thermal plasma in a floating electrode streamer corona discharge (FESCD) system is utilized for effective degradation of antibiotic ampicillin and non-steroidal anti-inflammatory drug (NSAID) ibuprofen. It was found that, after 3 h of plasma treatment, 100% of ampicillin and 90% of ibuprofen was degraded in the solution. The energy yield (the amount of degraded contaminants by consuming 1 kWh of energy) was calculated to be 0.12–0.13 g/kWh. Total Organic Carbon (TOC) measurements showed 20% and 60% mineralization for ampicillin and ibuprofen, respectively. Hydroxyl radicals were found to play a major role in the degradation of both contaminants. Furthermore, in both cases, the formation of oxygenated by products implied a possible role of ozone molecules in the degradation mechanism. Finally, Fluorescence Excitation-Emission Matrix (FEEM) was utilized to track the degradation of the contaminants in the tap water through the change in fluorescence properties and the connections between FEEM signals and the identified degradation by products were outlined.

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.
