摘要：
It is found that a periodic change of the surface tension is generated at the gas-liquid interface of an aqueous Belousov-Zhabotinsky (BZ) medium. It has been confirmed that the difference of the surface tension of the iron-catalyst between [Fe(phen)3]3+ and [Fe(phen)3]2+ is the driving force of this rhythmic phenomenon. The rhythmic change of the surface tension is discussed in relation to the known effect of convective flow accompanied by the propagation of a chemical wave in the BZ reaction.
