Plasma activated water (PAW) has emerged as a viable technique for sterilization process since it contains some long-lived reactive oxygen and nitrogen species along with some very short-lived but strong oxidation agents such as hydroxyl radical (OH * ) and superoxide anion (O 2 − ). However, the concentrations of the reactive species such as nitrite, nitrate, and ozone are often insufficient in water for sterilization, or only a small amount of PAW can be generated. In this study, we developed a state-of-the-art approach by combining microbubbles (MBs) and plasma technology in a water recirculation system to enhance the dissolution of reactive species in a large amount of water. The investigations included plasma absorbing power measurement, visualization of plasma-activated microbubbles (PAMBs) generation, bubble size distribution, and the concentration measurements of various reactive species in water, after the air plasma jet and the PAMBs jet tr...

等离子体活化的微气泡喷射增强水中活性化学物质的溶解

血浆活化水（PAW）已成为一种可行的灭菌方法，因为它含有一些长寿命的活性氧和氮，以及一些寿命很短但很强的氧化剂，例如羟自由基（OH *）和超氧阴离子（ O 2-）。但是，水中的亚硝酸盐，硝酸盐和臭氧等反应性物质的浓度通常不足以进行灭菌，或者只能产生少量的PAW。在这项研究中，我们通过在水循环系统中结合微泡（MBs）和等离子体技术开发了一种最新技术，以增强反应性物质在大量水中的溶解。调查包括等离子体吸收功率测量，等离子体激活微气泡（PAMB）生成的可视化，气泡尺寸分布，
