摘要：
Well-separated square wave voltammetric peaks for uric acid, dopamine and ascorbic acid were observed at an ultrathin polypyrrole-tetradecyl sulfate film modified gold electrode, which can be used for simultaneous determination of these species in the range of 1 to 500 mu M with good reproducibility.
