Oscillatory phenomena. Application of the D'Alba–Di Lorenzo model to the Bray–Liebhafsky system and others derived from it

The model proposed by D'Alba and Di Lorenzo, which explains oscillations by supersaturation and phase exchange, has been applied to the Bray–Liebhafsky system (hydrogen peroxide, potassium iodate and sulphuric acid), the Briggs–Rauscher system (hydrogen peroxide, potassium iodate, sulphuric acid, manganous sulphate and malonic acid) and the arsenite–iodate–chlorite system.The mechanisms of these reactions and the roles of the phase exchanges have been elucidated. The role of the catalyst and of some of the organic substrates is discussed, along with an interpretation of some of the experimental results.
