Ion-Selective Electrode for the Determination of Gold Based on Safranine O Tetrachloroaurate(III)

Abstract
A liquid-state ion-selective electrode is described for the determination of gold. The electrode, which is based on Safranine 0 tetrachloroaurate(III), gives near Nemstian response in the pAuCl4 range 6.6 to 3.6.
