A Potentiometric Study of the Briggs-Rauscher Oscillatory Reaction in a Solution of Ionic Surfactants and Tetrabutylammonium Hydrogensulphate

Popis výsledku v původním jazyce

The concentration effect of ionic surfactants was investigated on the Briggs-Rauscher oscillatory reaction in a stirred batch reactor at 25 °C in both the absence and presence of an ionic surfactant. In the presence of the anionic surfactant, the induction period and the oscillation period increase markedly, and the amplitude of oscillations decreases ith increasing concnetration of sodium dodecylsulphate. These effects have been observed when the concentraion of surfactant is much higher than its critical micelle concentration. Another effect on IP and OP has been observed in the presence of cationic and zwitterionic surfactants. A decrease in IP lerads to its extinction at a ceratin concentration and at the same time, chemical oscillations divide into two series of chemical oscillations. TBAH does not have a major influence on IP and OP of the BR oscillatory reaction. The observed effects are explained in terms of micellar catalysis or inhibition in different extens of individual reactants solubilisation respectively.
