Abstract:In the present research, a microneedle Cu (II) selective electrode based on conducting polypyrrole (PPy) doped with 8-hydroxyquinoline-5-sulfonic acid (8-HQS) is introduced. 8-HQS which has been incorporated into the polypyrrole backbone during electropolymerization acts as an active ionophore for Cu (II) ion recognition. Several relevant factors affecting the sensor performance have been investigated and optimized. The proposed electrode showed a linear response over the concentration range of 1.0 × 10−5 to 1… Show more
“…The performance characteristics of the proposed electrode were compared with those of previously reported electrodes for the determination of copper ions [38][39][40][41][42][43][44][45][46][47][48] and are summarized in Table 4. The proposed electrode shows a better selectivity, wide linear range and lower detection limit as compared to the earlier reported electrodes for copper ions.…”

A novel potentiometric and voltammetric sensor based on an ionophore (E)-3-(((2-((2 aminoethyl)amino)ethyl)imino)methyl)-4H-chromen-4-one (ICU) has been developed for the detection of Cu(ii).
