摘要：

The differential pulse voltammetric (DPV) method-with a glassy carbon electrode was used for the determination of 3,3’ 5,5’-tetramethy lbenzidine (TMB), o-tolidine and benzidine in the acidic media. The pulse amplitude, interval time and scan rate of DPV are optimized to be 50 mV, 0. 5 s and 10 mV/s, respectively. The peak current, is proportional to the concentration of TMB and its analogues, the linear range is from 10mol/l to 10mol/l. The electrochemical behaviour of the compounds is discussed. The chemical poisons can be determined directly, or indirectly by the extraction in the waste water of chemical industry and laboratory.
