Transformation of the structure and adsorption properties of bentonite during physical and chemical treatment

Abstract The paper presents the results of studies effect electromagnetic, ultrasonic and acid treatments on structure adsorption index alkaline-earth bentonite modified with nanoparticles silicon oxide aluminum. Studies have shown that contribute to an increase in capacity by 5, 10, 25%, respectively. Modification stabilized nanodispersed hydrosols amorphous (6-10.5 nm) crystalline boehmite (3.5-4 0.1-0.5 wt. % subsequent microwave allows its for methylene blue cation exchange up 40%. And during combining preliminary activation suspension sodium carbonate it 80%. properties is due a double homogeneity structure, dispersion specific surface area aluminosilicate particles transformations phase composition. As result, through use advances field nanotechnology, physical chemical effects, technology modifying natural aluminosilicates based has been improved, which makes possible significantly characteristics materials it.
