摘要：

The intake of sufficient amounts of vitamin C (ascorbic acid) is necessary for good human health. Therefore, simple, rapid methods for determination of the exact amount of vitamin C in human plasma are important for assessment purposes. A pencil graphite electrode was used to quantitate the amount of vitamin C in human plasma samples. The results indicated that the anodic peak current for ascorbic acid was linear in the concentration range of 10(-6) to 10(-4) M with a correlation coefficient of 0.9998. The obtained detection limit for AA using this amperometry technique was 1.18 x 10(-6) M.
