Destruction of Decachlorobiphenyl Using Supercritical Water Oxidation
Bibliographic record
Abstract
A microreactor (50-nL), batch reactors (6-mL), and a flow reactor (11.3-mL) were used to study the oxidation of decachlorobiphenyl (10-CB) in supercritical water. In the microreactor experiments, it was found that complete dissolution of 10-CB occurred at excess O 2 (>93%) and that both hydrolysis and oxidation contributed to 10-CB destruction. In experiments performed with the batch reactors, at excess O 2, 99.2% and 100% 10-CB could be destroyed in SCW without and with Na 2 CO 3, respectively. Addition of the neutralization agent Na 2 CO 3 promoted the destruction rate and reduced reactor corrosion significantly. A reaction mechanism for 10-CB destruction was proposed and this was examined further in flow experiments, where we found that 100% destruction could be achieved.

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.
