Abstract:	利用汞膜修飾金與碳纖維電極，研究金屬(銅、鈷、鎳與鋅)錯合物之伏安行為。將汞膜修飾金絲電極當做電化學偵測器( electrochemical detector, ECD ) 之電池的工作電極連接高效能液相層析儀，測定藥物毛果芸香鹼含量。 The voltammetric behaviors of metal chelate namely copper, cobalt, nickel and zinc in the presence of pilocarpine on thin-film mercury modified gold and carbon fiber electrodes have been studied. Cobalt (II) forms a labile chelate with pilocarpine in0.1 M lithium perchlorate, which subjected to differential pulse voltammetry at mercury coat–ed carbon fibre and gold wire microelectrodes, respectively, give rise to a catalytic phenomenon which can be utilized for the determination of pilocarpine in the pharmaceuticals. The gold with surface deposit of mercury was used as sensor in liquid chromatography-electrochemical detection (LCEC) to enhance the sensitivity and selectivity of analytical methods for the determination of trace concentration of pilocarpine.
