ABSTRACT
Based on the high solubility of azodicarbonamide (ADC) in hot solution and its electrostatic interaction with Nafion film,a new electroanalytical method was developed for the determination of ADC by using Nafion film electrode.The effect of temperature on the solubility of ADC and the mechanism of the reduction reaction of ADC on Nafion film electrode were investigated.Under the experimental conditions such as water bath at a constant temperature of 80 ℃,pH 6.0 and optimal test parameters,the differential pulse voltammetric response was proportional to the concentration of ADC in the range of 0.93-10.5 μg/L,and the detection limit was estimated to 0.58 μg/L.The relative standard deviation was less than 5.86 % and the recovery was 95.8%-104.0% for the determination of the ADC in flour samples.The semicarbazide and nitrofurazone did not interfere with the determination of ADC.
