A reagentless renewable N,N '-diphenyl-p-phenylenediamine loaded sensor for hydrogen sulfide
The electrochemically induced reaction of sodium sulfide with N,N′-diphenyl-p-phenylenediamine (DPPD) has been studied in aqueous solutions (pH 1-7) at glassy carbon (GC) electrodes. The DPPD indicator has been shown to form a thin film on the electrode surface capable of sensing sulfide at the trip...
