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.
A procainamide-selective electrode was constructed and applied for the determination of procainamide concentration in blood serum. The detection limit was 1.5 pg ml-', but determination down to 0.5 pg ml-' was possible with an appropriate calibration. The results correlated well with those obtained
