Abstract

The dynamic evolution of the oscillatory Belousov-Zhabotinsky reaction upon addition of increasing amount of the non-ionic polymer polypropylene glycol with molecular weight 425 g mol(-1) (PPG-425) was investigated in a stirred-batch reactor by monitoring the Ce(IV) absorbance changes. The oscillatory parameters are significantly altered by the presence of the polymer.The findings obtained in the present work revealed that the PPG-425 is not only more effective, than other polymer previously [R.
