Ion-Selective Electrode for the Determination of Perrhenate Based on Brilliant Green Perrhenate

Brilliant green perrhenate has been applied in a liquid-state ion-selective electrode for the determination of perrhenate. Near Nernstian response is obtained in the range 10−5 − 10−2 M perrhenate, and the response is independent of pH in the pH range 5.0 − 7.2.
