![]() The current responses were exactly total addition of sodium azide and buffer current responses. A well-separated peak of sodium azide was observed in its mixture with the buffers, resulting in selective sodium azide detection. Wide range of buffer concentration was examined. Hydrogen-terminated BDD was fixed for the investigation since it showed much better sensitivity for azide oxidation in comparison with the oxygen-terminated one. Three important saline buffers, ADA buffer (N-(2-acetamido) iminodiacetic acid), sodium EDTA and imidazole, were investigated. N2 - Direct detection of sodium azide was examined by using highly boron-doped diamond (BDD) electrodes in some physiological saline buffer solutions. T1 - Direct electrochemical detection of sodium azide in physiological saline buffers using highly boron-doped diamond electrodes Simple, selective, good sensitivity and excellent reproducible detection make the diamond electrodes very attractive for numerous electroanalytical applications.", Validation was achieved by the comparison with the sample concentrations given by the manufacturer. Sodium azide concentrations of 5 μg mL-1 were detected in both samples with the R.S.D.s of 0.07 and 2.37%, respectively. The present method was evidenced to be available for direct detection of sodium azide in two samples of commercial diluents for cell counting. Simple, selective, good sensitivity and excellent reproducible detection make the diamond electrodes very attractive for numerous electroanalytical applications.Ībstract = "Direct detection of sodium azide was examined by using highly boron-doped diamond (BDD) electrodes in some physiological saline buffer solutions.
