Copper(II)-selective electrodes based on macrocyclic compounds
Abstract
Poly(vinyl chloride) based membranes of 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene diperchlorate and 3,5,7,7,10,12,14,14-octamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene diperchlorate with dibutyl phthalate (DBP) and dioctyl phthalate (DOP) as plasticizing solvent mediator show a Nernstian response for Cu2+ ions over a wide concentration range (1 × 10–5–1 × 10–1 mol l–1) between pH 1.9 and 5.2. These electrodes have been found to be chemically inert and of adequate stability, with a response time less than 30 s. The electrodes are selective over a large number of cations, including HgII, and anions such as Cl– and Br– cause no interference. These electrodes work satisfactorily in partially non-aqueous media and have been used as indicator electrodes in potentiometric titrations of Cu2+ with EDTA.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
