Abstract
ABSTRACT Micellar enhanced ultrafiltration (MEUF) represents a potentially attractive tool for the removal of different contaminants from waste waters. The work presented in this paper was aimed at investigating the use of MEUF to remove 4,4'-isopropylidenediphenol [also known as 2,2-bis(4-hydroxyphenyl) propane and commercially available as bisphenol A or DIANE] from aqueous streams. Three surfactants, sodium dodecylsulphate (SDS), hexadecyltrimethyl ammonium bromide (CTAB) and alkylpolyglucoside Glucopon 215 SCUP (APG) were used to form the micellar structure both in the absence and in the presence of NaHCO3 as an electrolyte. CTAB which form cationic micelles gave the best performances in terms of bisphenol A rejection and micelle loading capacity. This may be as a result of the influence of various factors including the existence of a preferential interaction between the positive charge of the ammonium site of CTAB and the n -electron cloud of the aromatic rings of bisphenol A, as well as differences in interphase water penetration, micelle structure and chain packing and folding.

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 it
