The typical cathodic waves were observed in the acidic and neutral unbuffered solution of vitamin B1. The height of the wave became greater with increased concentration of vitamin B1, but its relationship was complicated by the effect of hydrogen ion concentration. The effect of buffering on the shape of polarographic wave was observed. When the concentration of the buffer decreased, the diffusion current became more distinct and more determinable. From the experimental results it was presumed that their electrode reactions were due to the reduction of vitamin-B1 and the catalytic discharge of hydrogen ion in the presence of vitamin B1 or its reduction product. The surface activity of vitamin B1 was seen in the observation that it well suppresses the maximum wave of oxygen.
