摘　　要： 研究了硫酸溶液中不同浓度甲醇的循环伏安行为。结果表明:甲醇氧化峰的峰电流与其浓度有着很好的线性关系,因此可以用循环伏安法来定量地测定硫酸溶液中甲醇的浓度。用自制的电解池测试Nafion117膜的甲醇渗透率,结果表明:经过5 h渗透后,Nafion117膜的甲醇渗透率为3.952×10-7cm2/s。 CV behavior of different concentrations methanol in H2SO4 solution was studied. The results showed that methanol oxidated peak currents had a good linear relation with methanol concentration. Therefore, CV method could be applied to measure quantitatively the concentration of the methanol in H2SO4 solution. An electrolytic cell was designed to test the methanol penetrability of Nation 117 proton exchange membrane. The results showed that the methanol penetrability of Nation 117 membrane was 3.952×10^-7 cm^2/s after penetrating 5 h.
