咖啡因属生物碱,是中枢神经兴奋药物之一~[1]。目前,咖啡因的常用测定方法有紫外分光光度法~[2]和高效液相色谱法~[3]等.电化学测定方法已有报道~[4～6],但尚未见到利用Nafion聚合物涂层碳纤维微电极的伏安测定方法.本文提出了一种简单易行的碳纤维微电极及其Nafion聚合物涂层的制造方法.得到了利用该电极微分脉冲伏安法测定咖啡因的最佳体系为
Caffeine is an alkaloid, is one of the central nervous excitement drugs ~ [1]. At present, the commonly used determination of caffeine UV spectrophotometry ~ [2] and high performance liquid chromatography ~ [3], etc. Electrochemical detection methods have been reported ~ [4 ~ 6], but have not yet seen the use of Nafion polymerization Voltammetric Determination of Material-coated Carbon Fiber Microelectrodes This paper presents a simple and easy-to-use carbon fiber microelectrode and its manufacturing method of Nafion polymer coating.It has been obtained that the differential pulse voltammetry Good system for
