✦ Synopsis

Acoustophoresis has been used to investigate the interaction between suspended mineral oxides ( SiOp and AlaO,) and aqueous solutions of cobalt(H) chloride, molybdenum(II1) chloride and ammonium heptamolybdate (AHM) as a function of the pH. The measured electrokinetic sonic amplitude (ESA) is directly related to the c-potential and gives information on the iso-electric point of the mineral oxides, that are used as supports for catalysta. The interaction between the solutes and the suspended mineral oxides is an important parameter for the preparation of supported catalysts, which can be studied perfectly by means of acoustophoresin. The specific adsorption of cobalt and molybdenum on silica and alumina has been considered.
