【摘要】 <正> I. M. Kolthoff等曾指出甲基橙在滴汞电极下可被还原,我们在试验中发现:在Na₂CO₃底液中,于示波极谱仪上,甲基橙有一良好的极谱波,其峰电位在-0.75伏,在6×10^-6～6×10^-5M间,峰高与浓度成线性关系。常见离子和若干指示剂干扰不大。在实验的基更多还原

【Abstract】 This paper, a method determination of methyl orange by oscilloscophic polarography is given.The results show that there is a good reduction peak of methyl orange at 0.75 V.The hight of peak is directly proportional to concentration within6×10^?～6×10^-5.更多还原
