[求助] 关于循环伏安电极旋转铂微电极可以用什么电极代替?

文献中如下描述:Linear and cyclic voltammograms (CV) were measured at room temperature in a three-compartment cell. The potential of the working electrode was measured against an Ag, AgCl/3 M KCl electrode as the reference electrode. A platinum wire was used as a counter-electrode. Sample Text(d= 2 mm) was used as the working electrode. Prior to the experiments, the microelectrode was polished with alumina suspension, and washed with water and chromic sulfuric acid. The cell was assembled and filled with a 10^3 M solution of a heteropolyacid in HClO4 (0.5 M)/CH3CN (1:1). Before and during the tests, the cell was deoxygenated by purging with N2.
如果简单测循环伏安,工作电极是不是可以不用旋转电极?用普通的铂片电极可以吗?或者必须要用微电极?我不太懂旋转电极和微电极的区别,求解!万分感谢!

你根据这篇文章的原因是神马啊,你自己要研究什么问题,用不用微电极取决于你的目的的,要不要研究机理啥的,cv本身啥样电极都能扫的
