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.
