eng	Possibilities and limitations of the determination of zinc(II) at gallium film electrodes. An initial study	In this paper, basic electroanalytical properties and behaviour of the gallium film-plated electrodes (GaFEs) are presented. Being prepared by electrodeposition and plating onto two different carbonaceous electrode substrates, the following experimental characterisation of the individual GaFEs has been focused on their possible employment in stripping voltammetry. The most satisfying performance and fairly low background currents were achieved in acetate buffer or diluted hydrochloric acid, when using the square-wave voltammetric mode. The electroanalytical performance of a method with GaFE has been tested on model determinations of Zn(II) ions with satisfactory results.	gallium film(s); glassy carbon- and carbon paste electrode substrates; anodic stripping voltammetry; zinc; determination
