Multi-templated Pb-Zn-Hg Ion Imprinted Polymer for the Selective and Simultaneous Removal of Toxic Metallic Ions from Wastewater
Bibliographic record
Abstract
A multi-templated Pb-Zn-Hg ion imprinted polymer was synthesized to demonstrate the selective and simultaneous removal of the named targeted ions. Molecular Imprinting Technology was employed, guided by thermal bulk polymerization method, methacrylic acid as the functional monomer and ethylene glycol dimethylacrylate as crosslinking agent in the presence of the initiator azobisisobutyronitrile; Pb(II), Zn(II) and Hg(II) ions as template ions, and 1,10-phenanthroline as the complexing agent. Rigorous, optimal template removal method was employed. Physical and chemical properties of the sorbent were investigated using Fourier Transform Infrared Spectroscopy, X-ray Diffraction and Atomic Force Microscopy. Operational parameters: time, pH and sorbent dosage for the rebinding batch experiments were optimized and found to be 15 min, 7.5 and 666.7 mg/L respectively. Percentage recoveries of the removed targeted ions from spiked samples were: 92.14 ± 0.16%, 106.09 ± 0.17% and 99.86 ± 0.04%. The synthesized sorbents showed good selectivity towards the targeted metal ion by removing 90% - 98% of the templated ions as compared to 58% - 62% of the competitive ions.

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.
