【Abstract】 The adsorptive wave of folic acid in the Britton-Robinson buffer solution （pH=6.5） was studied with linearly changing potential polarography. The results show that the electrode reaction is a 2e-2H⁺ reversible, the polarographic wave obeys the equation of the adsorptive reversible wave. The diffusion coefficient of folic acid was （2.50±0.03）×10^-6cm²/s, and the mechanism of the electrode process has been discussed.更多还原
