摘要: 利用交流电化学热方法测定了Br-/Br2和Pb/Pb2+电极的电极反应熵变.在动电位情况下利用该方法研究了聚吡咯电极反应.结果表明经碱溶液处理后聚吡咯电极的电化学活性明显下降,但从交流电化学热性质看,它还部分保留了原先聚吡咯电极的电极反应特性.

Abstract: The values of entropy change for Br/Br_2 and Pb/Pb~2+ electrode reactions were measured by use of the ac electrochemicalthermal method. The influence of alkaline pretreatment on the electrochemical behavior for a polypyrrole electrode was also investigated by this method. It was found that after alkaline pretreatment the eletrochemical activity of polypyrrole electrode was decreased obviously, but it kept partly electrochemicalthermal characteristic as same as that before pretreatment.
