Аннотация
The possibility of using diantipyrylmethane as an ionophore component of a lead-selective electrode membrane was assessed. Membrane composition (wt %) was optimized: polyvinyl chloride (31.89), dioctyl sebacate (63.81), diantipyrylmethane (2.50), and oleic acid (1.80). The proposed model of the electrode works in the concentration range of 1 × 10–5–0.1 M with a detection limit of 2 mg/L. A slope of the electrode function of the diantipyrylmethane-based electrode is 29.4 ± 0.5 mV/pPb. Concentration of Pb(II) ions in various samples was determined.
