Abstract: The application of chemical oscillating reactions to chemical analysis was investigated. It was found that Belosov-Zhabotinsky reaction system is a dynamic de.ter-mination system of good selectivity and sensitivity to thallium(or mercury)ions. The change of the period of oscillating curve of B-Zreaction is linearly proportional to the amount of Tl(Ⅰ)(Hg(Ⅱ)) existing in the system, which can be used to determine 0.08~10 ppm Tl(Ⅰ)(or Hg(Ⅱ)). The mechanism of this analysis system is discussed by means of the Monte Carlo simulation technique, and the results agreeing with the experimental fact were obtained.
