Abstract:
The detecting method for low concentration of TNR by derivative polarography was proposed. Quantitative detection was carried out at selected polargraphic peaks,-0.5 V and -0.75 V. The relative standard curve, linear range and detection limit were obtained. Meanwhile, interference and recovery experiments were also studied and experimental conditions were optimum. The results show that this method have a wide linear range and lower detection limit.
