【Abstract】 The authors have chosen the optimum conditions for preparing coated wire silver/sulphur ion-selective elcctrodes (i. e. Ag/Ag2S), have also determined various performances of the electrodes. With respect to the reversibility and the resistance to oxidation of the electrodes, defferent conclusions from the literature have been obtained.更多还原
