摘要：
The physicochemical properties of air nanobubbles (Air-NBs) are the basis of their wide application. In this study, the physicochemical properties of Air-NBs produced by the principle of hydrodynamic cavitation, including the particle size distribution and zeta potential, were studied on the nanoparticle size-zeta potential analyzer. The effects of operating pressure, electrolyte concentration, pH and temperature on the physicochemical properties of Air-NBs were investigated, as well as the stability of Air-NBs respectively in deionized water and CaCl2 solution. The results showed that the higher the pressure of the nano bubble generator, the larger the proportion of small particle size of Air-NBs, and the addition of electrolyte helped to reduce the particle size of bubbles. The average particle size distribution of Air-NBs decreased with the increase of electrolyte concentration, pH and temperature. However, the coalescence between bubbles was ascribed to the gradual increase of the particle size with time going. The Air-NBs particle size in the two solutions was monitored online. It was found that the Air-NBs could exist in the solutions for 5 days. The stability of Air-NBs in solution can be explained reasonably through DLVO theory and zeta potential effect. © 2022 Chemical Industry Press. All rights reserved.
