Analytical characteristics of electrodes selective for cationic phospholipid–Ba 2+ complexes

  • E. P. Golovei
  • V. I. Tkach


The interaction between organic cations of phospholipids products of their hydrolysis with the PMo12O 40 3− heteropoly anion was studied. A procedure was proposed for the direct potentiometric determination of phospholipids using ion-selective electrodes bearing poorly soluble ion pairs formed by the complexes of lecithin or ethanolamine glycerophosphate and Ba2+ and PMo12O 40 3− heteropoly counter anion as ionophores. The procedure is simple, rapid, sufficiently sensitive, and selective.
