Adsorption and Electrosorption of Ethyl Xanthate and Thiocyanate Anions at High-Area Carbon-Cloth Electrodes Studied by in Situ UV Spectroscopy: Development of Procedures for Wastewater Purification
Bibliographic record
Abstract
Adsorption and electrosorption behavior of ethyl xanthate (EtX - ) and thiocyanate (SCN - ) anions, individually and when they are together in a solution, were studied at high-area C-cloth electrodes by in situ UV spectroscopy in relation to development of methodologies for purification of industrial wastewaters. The employment of straightforward, yet demonstrably useful spectrophotometric techniques of kinetics and scanning kinetics is described. Adsorption isotherms of EtX - and SCN - were also derived. However, EtX - was found to decompose to a small extent during electrosorption on C-cloth and/or Au or Pt surfaces, causing some interference with the spectrophotometric analysis of SCN - at 215 nm. After long prior contact of the C-cloth with water, the adsorption rates of EtX - and SCN - are somewhat increased. Competitive adsorption studies show that SCN - ion does not become adsorbed on the C-cloth in the presence of EtX -, thus demonstrating a remarkable discriminatory effect.

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.
