Conclusions

  1. 1.

    Silicotungstic heteropolyacid is sorbed by silica gels, activated charcoal, and γ-Al2O3 from water and from organic oxygen-containing solvents, forming three formations distinguishable by electron microscopy.

     
  2. 2.

    The relative proportions of the surface forms are determined by the type of substrate, solvent, and the HPA concentrations on the substrate. The most uniform covering is achieved when HPA is adsorbed from ethyl acetate.
