论文摘要
离子溶液的电导率在低离子浓度高达几毫米的低离子浓度下被充分了解，但是在自然界和技术应用中仍然很常见的较高浓度下很难解散。最近在低电场上为单价电解质提出了高浓度电导率的模型。该模型依赖于应用随机密度功能理论，并使用修改的静电对势抑制了非物理，短距离静电相互作用。在这里，我们将理论扩展到多价离子以及高电场的高电场，在这种高电场上，欧姆定律被称为维也纳效应。我们的结果与实验和最近的模拟非常吻合。
The electric conductivity of ionic solutions is well understood at low ionic concentrations of up to a few millimolar but becomes difficult to unravel at higher concentrations that are still common in nature and technological applications. A model for the conductivity at high concentrations was recently put forth for monovalent electrolytes at low electric fields. The model relies on applying a stochastic density-functional theory and using a modified electrostatic pair-potential that suppresses unphysical, short-range electrostatic interactions. Here, we extend the theory to multivalent ions as well as to high electric fields where a deviation from Ohm's law known as the Wien effect occurs. Our results are in good agreement with experiments and recent simulations.
