摘要
本文用线性变位极谱法对B.R.缓冲溶液(pH6.5)中叶酸的吸附波进行了研究,证实它是一个2e-2H^+可逆反应,极谱波符合吸附可逆波方程式。测定了叶酸的扩散系数,并对电极反应机理进行了探讨。
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^(-6)cm^2/s, and the mechanism of the electrode process has been discussed.
