Vsj. Craig et al., COMMENT ON DEFORMATION OF FLUID INTERFACES UNDER DOUBLE-LAYER FORCES STABILIZES BUBBLE DISPERSIONS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 57(6), 1998, pp. 7362-7363
In a recent publication it was suggested that a simple double-layer fo
rce could be used to explain the unexpected effect of electrolytes on
reducing air bubble coalescence in aqueous solutions. We suggest here
that this force cannot explain the observed behavior or the ion-pair s
pecificity of the phenomenon, and that an adequate explanation has yet
to be found.
