Annotation	A simple apparatus (electrolyzer) and a reliable procedure were developed for the preparation of mercury films of exactly defined thickness on a silver solid amalgam substrate. Constant concentration of Hg(II) in the electrolyzer is ensured by dissolution of an anode from silver paste amalgam. Small volume of electrolyte, which can be used repeatedly many times, and paste amalgam preventing the spillage of liquid mercury substantially decrease the danger of environmental contamination with mercury. Parameters and behavior of mercury film electrodes on silver solid amalgam substrate (MF-AgSAE) were compared with polished silver solid amalgam electrode (p-AgSAE) which does not contain liquid mercury, with mercury meniscus modified silver solid amalgam electrode (m-AgSAE), and with hanging mercury drop electrode (HMDE).
