Abstract:

This study aims to investigate the effects of a probe and a cup horn on the de-agglomeration efficiency in ultrasound vibration processes. TiO₂ and Al₂O₃ nanoparticle dispersions were prepared in distilled water at a concentration of 50.0 mg/mL followed by treatment with a dispersion stabilizer(100% FBS)and ultrasound vibration at 20 kHz and 35% amplitude for 10 min by a probe and a cup horn, respectively. The average sizes of dispersed TiO₂ and Al₂O₃ nanoparticles were measured by a dynamic light scattering device. Compared to dispersion with the probe sonicating, the average sizes of TiO₂ and Al₂O₃ particles sonicated by the cup horn are markedly smaller at time points of 30, 60, 120, and 180 min. The TiO₂ and Al₂O₃ particle size distributions of cup horn-treated suspensions were narrower than those of probe-treated suspensions at time points of 120 and 180 min. It is suggested that the cup horn has a higher efficiency than the probe in dispersing nanoparticles. The cup horn is better than the probe for processing multiple small sample vessels simultaneously. Indirect cup horn sonication is ideal for processing pathogenic and sterile samples.
