摘要：

<正> Recently there has been a great interest in detection of catecholamines in the presence of ascor-bic acid. These two species have been found in brain, urine, and blood specimens, electro-chemical detections of catecholamines and ascorbic acid at electrodes are based on their "easy"oxidation reactions. Detection problems for the catecholamines in real samp1es are the interfer-ence from ascorbic acid, which oxidizes at the same potential as catecholamines. The purpose
