Modification of PDMS Membrane by Organo-montmorillonite for Pervaporation of Acetic Acid over Water
Bibliographic record
Abstract
An organo-montmorillonite filled polydimethylsiloxane membrane was developed for recovering acetic acid from its dilute solution by pervaporation. The filled membrane was prepared by cross linking reaction in solution using cetyltrimethylammonium bromide (CTAB) pillared montmorillonite. XRD and SEM were applied to characterize the filled membrane morphology. The results showed that the filled membrane with organoclay silicate layers not only showed the most optimal thermal stability but also exhibited the highest separation factor for the pervaporation of acetic acid over water when the filler content was around 7.4%(ω). A possible mechanism was proposed that the enhanced selectivity and permeability were derived from the effect of permeable reactive passageways for adsorptiontransportdesorption because of the ordered nano-layered structure and hydrophobic capacity of organo-montmorillonite in the hybrid membrane.

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.
