The prepared AuNPs/CNT/poly(NB)/GCE was used for as a sensor platform for individual and simultaneous determination of hydrazine and nitrite. Electrodes were characterized by HRTEM, SEM, XPS, EIS. The LOD for nitrite and hydrazine was 5.0 mu M and 3.1 mu M at AuNP/CNT/poly(NB)/GCE, respectively. Also, sensitive amperometric determinations of hydrazine and nitrite were performed and LOD were calculated as 0.33 mu M and 0.68 mu M, respectively. The method was applied to sausage and river water samples and recovery results were obtained in the range 85-115 %.EnglishELECTROCATALYTIC OXIDATIONGOLD NANOPARTICLESPASTE ELECTRODEVOLTAMMETRYFABRICATIONREDUCTIONSULFITESAMPLESCOBALTSENSORArticle
