A coated-wire gold(III)-selective electrode based on the 1,2,4,6tetraphenylpyridinium tetrachloroaurate(II1) ion-pair is described. The response is Nernstian in the gold concentration range lo-'-3 X 10d (slope 59.0 mV/pAu). Of the 22 ions tested, only the interference of thallium(II1) is important.
