The possibility of the heavy metal ions determination and retention (with the example of copper ion) by a new Schiff base complex electropolymerization has been studied from the theoretical point of view. It has been shown that, despite of the absence of the surface instabilities, the probability of the oscillatory instability will be more expressed than in the case of the classical assisted polymer electrochemical deposition. Nevertheless, the steady-state stability is efficient, either from electronalytical, or from electrosynthetical point of view.
