Determination of traces of thallium using the transient chaotic regime in the Belousov–Zhabotinskii oscillating chemical reaction Original Research Article

New method is developed for the determination of traces (<10−9 M) of thallium(I) in aqueous solutions. The method is based on an effect of thallium(I) ions on transient chaotic regimes in the Belousov–Zhabotinskii oscillating chemical reaction. The optimum conditions for the determination has been determined. The detection limit is ≤10−12 M. There are few interferences at low concentrations.
