Abstract: The features and applications of silver amalgam electrodes in electroanalysis of
pharmaceuticals and vitamins are summarized in this review. The state-of-the-art in the
preparation and construction of solid silver amalgam electrodes for prolonged and userfriendly
use is presented. Although not as widely spread as other electrode materials, silver
amalgam possesses a unique and viable combination of favorable electrochemical properties,
which are close to ideal mercury electrodes, non-toxic character, high durability and
mechanical stability, if properly prepared. Its capability of conducting the redox processes at
highly negative potentials is essential for the analysis of large number of bioactive organic
compounds. The review features also overview information for each application in drug or
vitamin analysis divided to the sections according to the construction variants of silver
amalgam electrodes.
