A weak chemiluminescence (CL) emission was observed upon mixing peroxynitrite (ONOO(-)) with dihydralazine sulfate (DHZS). Further experiments showed that carbonate media could enhance the CL emission significantly. Based on these observations, a novel flow injection CL method for the determination of DHZS is developed. The CL signal is linearly with DHZS concentration in the range of 0.01-3.0 microg mL(-1) with a detection limit of 3.6 ng mL(-1). The method was applied to the analysis of DHZS… CONTINUE READING
