Abstract:
A novel method combining visualization particle tracking with image-based dynamic light scattering was developed to achieve the in situ and real-time size measurement of nanobubbles(NBs). First, the in situ size distribution of NBs was visualized by dark-field microscopy. Then, real-time size during the preparation was measured using image-based dynamic light scattering, and the longitudinal size distribution of NBs in the sample cell was obtained in a steady state. Results show that this strategy can provide a detailed and accurate size of bubbles in the whole sample compared with the commercial ZetaSizer Nano equipment. Therefore, the developed method is a real-time and simple technology with excellent accuracy, providing new insights into the accurate measurement of the size distribution of NBs or nanoparticles in solution.
为实现对纳米气泡粒径的原位和实时测量, 将可视化粒子追踪与图像动态光散射技术相结合, 开发出一种新的测量方法.首先, 基于可视化方法, 利用暗场显微镜成像, 得到纳米气泡的原位粒径分布.然后, 采用图像动态光散射法, 对纳米气泡制备过程进行实时粒径监测, 并得到了样品池中纳米气泡在稳态下的纵向粒径分布.结果表明, 与商用ZetaSizer纳米粒子测量仪相比, 利用所提测量方法能够获得整个样品池中的纳米气泡粒径信息, 实验数据更详细, 结果更准确.因此, 该测量方法是一种准确性较高、实时简单的测量技术, 为准确测量纳米气泡和纳米粒子的粒径分布提供了一种新手段.
