• Mechanochemical treatment

Possibility of chemical linking of tungsten heteropolycompounds (HPC) of 12th row with activated silica surface has been studied. From the analysis of IR- and X-rayfluorescent spectroscopy data as well as differential thermal analysis of the samples. it was found that phosphorus-tungstic heteropolyacid reacts chemically with amine groups previously immobilized on the Silica Surface. Thermal stability, acidity, ammonia adsorption and other physiochemical properties of grafted heteropolycompounds have been also investigated.
