摘要：

The time difference (y) between the reaction of sulfamethoxazol with Br2 and the reaction blank solution with Br2 is directly proportional to the nascent concentration of sulfamethoxazol (C), a little surfeit of Br2 can make a slot on oscillogram of trace platinum-platinum electrodes. The slot can be used to indicate end point. In this paper, a new method for the determination of sulfamethoxazol is developed on the basis of the combination oscillography and kinetic analysis. This method is sensitive, simple, fast and no interference from solution color and precipitation.
