PREPARATION OF ALUMINUM POLYPHOSPHATE AND IMPROVEMENT ON ITS PHYSICOCHEMICAL PROPERTIES BY MECHANOCHEMICAL TREATMENT

Abstract

Aluminum polyphosphate was prepared and then treated with the planetary mill for several minutes. The milled samples were characterized by inductively coupled plasma, X-ray diffraction, and Fourier transform infrared spectroscopy. SEM images, particle size distribution, specific surface area, surface acid strength, and amount of acidic sites of the materials were also measured. Furthermore, the catalytic and adsorptive properties of aluminum phosphate were also estimated.
