Possibilities of determination of thiocyanate ions, which play an important role in e.g. improving the quality of the nickel electrodeposits, were studied. Two different ways of voltammetric determination of thiocyanate ions in real samples (matrix in nickel electroplating solution) were investigated: formation of complexes with either mercury or copper. In both cases the determination was performed without any sample digestion. The best results were reached for desorption of the copper-thiocyanate complex from the mercury electrode surface with limit of detection 10 mug L-1.
