Abstract:
The in situ1H NMR technique was used to study the propagation of chemical waves during the liquid-phase Belousov–Zhabotinsky (BZ) reaction in a model fixed bed of grains consisting of chemically inert glass beads or quartz sand. The propagation of autocatalytic chemical waves in this bed is determined by the size of pores between the grains. The rate of wave front propagation is independent of the size of the grains involved in this bed but is much lower than that in the bulk of the homogenous aqueous phase. This may be attributed to the difference in the effective diffusion coefficients in the homogeneous liquid phase and in the bed.
