中文摘要: 采用一维漂移-扩散流体模型,对活性粒子在甲酰胺溶液中的传质进行了数值模拟。分析了等离子体处理甲酰胺溶液中5种主要活性氧粒子(OH、OH2、O3、O2- 、H2O2)的浓度和渗透深度。结果表明:在甲酰胺溶液中,O3和OH的渗透深度可以达到13~14 μm,高于水中的7~9 μm;O2-渗透深度为580 μm,约为其在水溶液中的50%;甲酰胺浓度在10-5~10-3 mol/L内,对活性氧粒子传质过程的影响较明显;溶液中O2对活性氧离子多样性有积极作用。这些现象表明,可以通过控制实际环境改变活性氧粒子的渗透深度。
Abstract:The numerical simulation base on a one-dimensional drift-diffusion model.The concentration and penetration depth of five main reactive oxygen species (OH,OH2,O3,O2-,H2O2) are analyzed in the formamide solution of plasma treatment.The penetration depths of O3 and OH increases to 13~14 μm in formamide concentration higher than 7~9 μm in the water.When the concentration and penetration depth of O2- is 580 μm,it is half as much as in the water.When the concentration of formamide ranges from 10-5~10-3 mol/L,the penetration depth of species is more affected.The initial concentration of O2 in the solution also has a positive effect on particle penetration.These phenomena suggest that the penetration depth of species can be changed by controlling the actual environment.
