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