Abstract
A simple procedure has been devised for reversing the passivation of the GCE that occurs during electrochemical analyses. Alumina polishing is unpredictable in that occasionally it may worsen the problem. The present procedure involves treating the GCE with a CrO3-H2SO4 solution. It is fast (30 seconds), reliable, and increases the responsiveness of the electrode above that obtainable by alumina polishing.
摘要
已经设计出一种简单的程序来逆转在电化学分析过程中发生的玻碳电极（GCE）的钝化。氧化铝抛光不可预测，因为偶尔它可能会使问题恶化。目前的程序包括用CrO₃-H₂SO₄溶液处理玻碳电极。它速度快（30秒）、可靠，并且能使电极的响应性比通过氧化铝抛光所能达到的更高。
