Аннотация:Thermal lensing is proposed for monitoring unstirred Belousov-Zhabotinsky reaction with a mixture of free Fe(II) and its chelate with 1,10-phenanthroline as a catalyst and a photometric indicator of the reaction process. The optimum initial concentrations of components for stable oscillations in system are found. The sensitivity and reproducibility of thermal lensing was compared to spectrophotometry and potentiometry by the model determination of bromide ions by its inhibition effect on the reaction kinetics.
