Description The experimental study of iodate-catalysed disproportionation of aqueous hydrogen peroxide, called the Bray-Liebhafsky oscillating reaction (BLR), was performed by using membrane introduction mass spectrometry (MIMS). The sequence of species O2, HIO2, HIO, and I2, which appear during the oscillation, was observed for the first time. The influence of ambient atmosphere, stirring rate, and temperature on the BLR was investigated. The contribution of gained results to the published models is discussed.
