Liquid–phase transport of plasma-generated reactive species toward large-scale plasma treatment for agricultural applications is experimentally studied. The liquid-phase reactive species in this study are generated by the contact of water solution with air–plasma effluent gas containing mainly low-solubility reactive species under elevated pressure, followed by spraying the plasma effluent gas dissolved solution into a target pathogenic conidium suspension. Low-solubility ozone in the liquid phase at the target is found to dominate the observed germination suppression effect, which also correlates with the gas-phase ozone density. The measured ozone concentration at the target is found to be ten times lower than the ozone concentration at saturation, estimated from Henry’s law with the measured gas-phase ozone density. The liquid-phase ozone loss mechanism during the transport of the sprayed liquid is interpreted as volatilization and reactions with co-dissolved species. The ded...

空气-血浆产生的反应性物种的液体喷雾传输,用于植物病害管理

实验研究了等离子体产生的反应物种向农业大规模等离子体处理的液相传输。这项研究中的液相反应性物质是通过在高压下使水溶液与主要包含低溶解度反应性物质的空气-血浆流出气体接触,然后将血浆流出物的气体溶解溶液喷洒到目标病原性分生孢子悬浮液中而产生的。发现目标处液相中的低溶解度臭氧占主导的观察到的发芽抑制效果,这也与气相臭氧密度相关。根据亨利定律,利用测量的气相臭氧密度,发现目标处测得的臭氧浓度比饱和臭氧浓度低十倍。喷雾液体运输过程中的液相臭氧损失机理被解释为挥发和与共溶物质的反应。的...
