Electrochemical behavior and kinetic parameters of vitamin B₆(VB₆) were investigated at poly-L-tryptophan modified glassy carbon electrode(PTRP/GCE) by cyclic voltammetry(CV),linear sweep voltammetry(LSV) and chronocoulometry(CC).Electrochemical results show that VB₆ electrochemical behavior exhibits an irreversible oxidation at 1.085 V(vs.SCE) with one electron transfer and one proton.The peak currents are linearly related to the square root of scan rates in a scan rate range of 20～400 mV/s.The effective area of PTRP/GCE A_eff and the diffusion coefficient D are 0.29 cm² and 1.961 2×10^-4 cm²/s,respectively.In a HAc-NaAc buffer solution of pH=3.0,the oxidation peak current of VB6 versus its conce-ntration exhibits a good linear relationship in a concentration range of 1×10^-4～5×10^-6 mol/L with a correlation coefficient of 0.993 1 and a detection limit of 1×10^-6 mol/L.The linear regression equation is i_pa(μA) =7.740+408.813c(mmol/L) and the recovery is 100.15%.
