采用边界元(BE)法对基于玻璃双微米管的产生/收集(G/C)体系的响应进行了模拟,对于各种不同几何形状的玻璃双微米管的收集率进行了计算;详细讨论了一个玻璃双微米管的形状对于收集率的影响,这些影响因素包括曲度、对称性以及产生管和收集管之间的厚度.另外,采用二苯基十八冠六(DB18C6)加速钾和钠离子在水/1,2-二氯乙烷(W/DCE)的转移反应体系对于模拟所得到的结果进行了实验验证.结果表明在扩散控制条件下的G/C体系,BE法可以有效地模拟几何对称的玻璃管的收集率.然而,对于几何形状不对称的玻璃管,模拟所得到的结果与实验结果有较大的差别.因此,在进行离子型产生/收集研究中,应该选择对称性好的玻璃管.
The Boundary Element (BE) method was used to simulate the response of a glass / double-tube-based G / C system and the collection rates of glass double-micron tubes of various geometries were calculated. The influence of the shape of a glass double-micron tube on the collection rate, including the curvature, symmetry, and the thickness between the tube and the collection tube, and the addition of diphenyl 18 crown-6 (DB18C6) to accelerate potassium and sodium The experimental results of the simulation in the transfer reaction of water in 1,2-dichloroethane (W / DCE) show that the BE method can effectively control the G / C system under diffusion control conditions However, for the asymmetric geometry of the glass tube, the simulation results obtained with the experimental results are quite different.Therefore, in the ionic production / collection of research, you should choose the symmetry Good glass tube.
