Mercury(II) Selective Membrane Electrode Based on Calix[2]thieno[2]pyrrole
Bibliographic record
Abstract
The construction, performance, and applications of mercury(II) ion selective electrode based on calix[2]thieno[2]pyrrole receptor are described. The influences of membrane composition and pH on the potentiometric response of the electrode were investigated. The electrode exhibits Nernstian response (27.8 mV per decade) for Hg2+ ion over a wide concentration range (1.0 x 10-6 to 1 x 10-2 M). The response time of the electrodes is 20 s for the solution of Hg2+ ions in the concentration range of 1 x 10-6 – 1 x 10-2 M. The selectivity coefficient values showed better sensitivity and selectivity of this sensor for mercury(II) ions over various mono-, di, and trivalent cations studied. The sensor was also applied as indicator electrode in the potentiometric titrations.

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.
