Catalytic brdicka-type systems in alternating-current square-wave voltammetry

Conventional kinetic and adsorption parameters of signals detected by alternating-current squarewave voltammetry in the catalytic systems cobalt(II)-NH3-cysteine (cystine) and nickel(II)-NH3-cysteine (cystine) in the presence of excess catalyst (metal ions) were discussed. The parameters for the optimization of the detected signals (mercury column height and mercury dropping rate) were considered. The characteristics of the cobalt(II)-NH3-cystine-containing protein indicator system were qualitatively compared with those of the model cobalt(H)-NH3-cystine system.
