摘要：

A rapid electrochemical method for in situ renewal of glassy carbon electrodes is described. A short, but 'severe', electrochemical treatment applied repetitively between successive voltammetric scans is shown to effectively remove passivating films. Hence, each voltammogram is recorded on a freshly activated surface. Prevention of electrode passivation is illustrated for materials, such as phenol, dihydronicotinamide adenine dinucleotide (NADH), chloropromazine, uric acid, butylated hydroxyanisole (BHA), or dodecyl sodium sulfate, known to produce severe loss of electrode activity.
