主 题：Ag2CO3-BaCO3 Ion-selective electrode Carbonate determination Heat exchange water
摘 要：A new all-solid-state carbonate ion-selective electrode was fabricated via electrochemical and ion-exchange reactions with Ag nanoparticles and Ag2CO3-BaCO3 as ion-to-electron transducer and ion-selective layer, respectively. This paper presented the detailed procedures of the construction of the electrode, the applications of the electrode in various experiments, and the corresponding chemical reaction principles involved. The fabricated electrode was characterized by means of scanning electron microscopy（SEM）, energy dispersive spectrometer（EDS）, and electrochemical analyses. The electrode exhibited stable linear responses to carbonate anions（10-5--10-1 mol/L） with average Slope of the curve being -26.56 mV per decade, and showed negligible responses to NO3, SO2-, and Sal- anions. The electrode was further used to measure the concentration of carbonate anions in boiler water. The measured concentration was lower than that determined via titration. Overall, the electrode exhibited the advantages of miniaturized size, robust construction, and compatibility with other equipment and thus could be ideally integrated into various sensor platforms to collect chemical data from industrial heat exchangers.
