但是，我昨天换成了另一个玻碳电极，仍旧是用的相同浓度的电解液，扫出来的CV图就好多了，只是峰电位差不在标准范围内，是怎么回事呢。今天我再改改浓度试试 。...

扫铁氰化钾 电位窗口应该在 -0.6---0.2 v之间， 铁氰化钾用1 mM in 0.1 M KCl即可；

我一般打磨完直接用超纯水冲洗，扫CV 峰间距在100 mV以内

那估计还是电极的问题吧...

或许是楼主你设置的扫速太大了，扫速太大峰就不明显了。你降个数量级试试？

今天换新的玻碳电极了，打磨完了用超纯水超声清洗的，峰间距110mv左右。...

嗯 感觉 现在好多paper都不太在意峰间距，别太大就成

祝贺...
