摘要
利用电化学原理来设计各种气体传感器已经越来越普遍,本文就硫化氢气体在Pt网电极上的电极响应行为进行了研究,确定硫化氢的最佳敏感电位在1.0V左右,其响应电流随硫化氢浓度的增大而增大。溶液中的溶解氧对电极的响应行为存在明显的影响。
It is more and more widespread to design gas sensors on the basis of electrochemical theory. This article has made a detailed research on the electrochemical behaviors of hydrogen sulfide on Pt electrode. It is determined that the optimum sensing potential of hydrogen sulfide on Pt electrode is about 1.0 volt. The response current increases with the increasing of hydrogen sulfide concentration. Dissolved oxygen is an important influence on the response current of Pt electrode.
