A new method for the determination of trace amounts of manganese(II) in aqueous solutions by its affect on some types of the chaotic regimes in the Belousov-Zhabotinskii reaction has been proposed. The method is based on the high sensitivity of some types of chaotic regimes of the BZ reaction to small perturbations of initial conditions (e.g., low concentrations of some metal ions). The experimentally obtained detection limit for manganese is 3 pg/ml.
