Abstract
The measurement of the catalytic current, caused by the interaction between cyanide and nickel(II)-ethanolamine complex enables the determination with the detection limit 0.4 μg l-1 with the relative mean deviation 0.90%. Direct fast pulse polarographic determination, based on the measurement of the anodic current has the limit 40 μg l-1 and the relative mean deviation 0.93%.
