Synthesis, transport and ionophore properties of α,ω- diphosphorylated aza podands: III. Liquid ion-selective electrodes based on phosphorylated aza podands

Abstract

Aza podands having side α-aminomethylphosphine oxide groups were prepared and used as electrode-active agents in liquid membrane ion-selective electrodes. A series of liqiud membrane electrodes sensitive to Cu2+ and Hg2+ cations were prepared on the basis of N,N-bis[di(n-hexyl) phosphorylmethyl]piperazine. The electrodes containing copper complexes with aza podands as ionophores exhibit anionic function toward lipophilic anions. Potentiometric and argentometric determination of iodide ions was performed with an iodide-selective electrode based on the mercury complex. © Pleiades Publishing, Inc., 2006.
