Detection of zinc(II) ion by using self-oscillation of the electrical potential across the water-oil-water liquid membrane

摘要

Oscillation of an electrical potential across a water-oil-water liquid membrane was measured in the presence of metal ion in one of the aqueous phases and a ligand in the organic phase, which likely forms a complex with Zn2+. By use of the formation of the complex around the interface, Zn2+ was detected through the measurement of the oscillation mode. [References: 7]
