Bidentate organophosphorus compounds as ionophores for calcium- and uranyl-selective electrodes

Abstract

Neutral bidentate organophosphorus compounds have been investigated as electroactive compounds for Ca²⁺- and UO₂²⁺-selective electrodes. The results obtained enabled Ca²⁺ and UO₂²⁺ electrodes to be developed and the optimum conditions for the operation of these electrodes to be determined. Some general conclusions on the nature of the selectivity of the ligands investigated are also presented.
