Effect of Focused Ultrasound on Residual Particle Size Distribution in Water

In this study, the amount of the radicals generated by high-intensity ultrasound radiated to the TiO2 suspension was evaluated through image processing for the degree of discoloration of methylene blue added to the suspension. As a result, we could obtain the result that in the case of 40 ml of distilled water, the 0.2 g of H2O2 with a concentration of 50 mM, the 5 g of TiO2 pellet with an average diameter of 3.85 mm, and 10 minutes the irradiating by ultrasound with an 22.7 $\times$ 10$^{3}$ (W/m$^{2}$) were the most efficient conditions for activating radicals generation.

“…In this study, we propose a new sonochemical synthesis method using a cylindrical piezoelectric vibrator, which can make a focused ultrasound in its inner space. [27][28][29] In this method, a ZnO nanostructure can grow efficiently. The distribution of ultrasound in the inner space is analyzed theoretically to estimate the distribution of the synthesized nanostructure.…”

We designed a zinc oxide (ZnO) growth device using a cylindrical piezoelectric lead zirconate titanate (PZT) vibrator. This growth device can be employed to realize a simpler and more efficient synthesis method using focused ultrasound. To confirm the effectiveness of the device, the distribution and nanostructure size were investigated under different ultrasonic powers and precursor concentrations. The size of the synthesized nanostructure was proportional to the precursor concentration and ultrasound intensity. The chemical effect of the ultrasound is more dominant than the mechanical one when the ultrasonic cavitation is generated. According to the results of the X-ray diffraction pattern and distribution, the synthesized nanostructure showed a high crystallinity and a populous distribution at the target area. Fig. 12.
