Delamination of Vermiculite Particle Using Ultrasonic Treatment

Popis výsledku v původním jazyce

Natural expanded vermiculite (particles size below 100 microns) was used for the investigation of exfoliation effect after hydrogen peroxide and/or ultrasonic treatment at 70°C. Powder samples were treated in water and in hydrogen peroxide solution withvariable concentration: 10, 30 and 50 vol.% of hydrogen peroxide. Delamination was monitored using X-ray diffraction methods and particle size distribution measurement. The significant reduction of the basal 001 peak intensity indicated the partial exfoliation of vermiculite particles after treatment with the highest concentration of hydrogen peroxide solution (50 vol.%). The particle size distribution measurement showed the reduction of average particle size in case of treatment in solution with 30 and50 vol.% of hydrogen peroxide concentration. To describe the mechanism of exfoliation, the content of Na, Ca, Mg, K, Si and Al in water solution after treatments were determined using the atomic emission spectrometry with inductive coupl
