Apukhtina, E. Kulapina, S. Mitrokhina] Cationic functions of selective electrodes based on tetraphenylborate salts of polyethoxylate complexes of Pb(II), Ba(II), Ca(II), Cd(II), and Zn(II) (M-PEO-TPB) are studied in solutions of these metal cations and polyethoxylates. It is shown that the linearity range of the electrode response, detection limit, and the slope of the electrode function are governed by the stoichiometry of reaction, stability, and solubility of complex [M-PEO]2+ cations in water. Lead-selective electrodes based on a Pb(II)-PEO-TPB compound exhibit the best parameters. The behavior of these electrodes in polyethoxylate solutions is studied and their performance characteristics (response time, potential drift, service life) are determined.
