离子溶液的连续模型:Poisson-Boltzmann及相关理论

A Brief Review of Continuous Models for Ionic Solutions: the Poisson-Boltzmann and Related Theories

Mao Su, Yanting Wang

摘要:

Poisson-Boltzmann(PB)理论是连续描述带电系统的最重要的理论模型之一。然而,它遭受忽略离子相关性,这阻碍了它的适用性更一般的带电系统以外的极稀的。因此,一些修改版本的PB理论的发展,以有效地包括离子相关。本文以离子溶液为研究对象,简要回顾了原始PB理论及其变体,包括场论方法、相关增强PB模型、Outhwaite-Bhuiyan修正PB理论和平均场论,并分析了它们的优点和局限性。

英文摘要:

The Poisson-Boltzmann (PB) theory is one of the most important theoretical models describing charged systems continuously. However, it suffers from neglecting ion correlations, which hinders its applicability to more general charged systems other than extremely dilute ones. Therefore, some modified versions of the PB theory are developed to effectively include ion correlations. Focused on their applications to ionic solutions, the original PB theory and its variances, including the field-theoretic approach, the correlation-enhanced PB model, the Outhwaite-Bhuiyan modified PB theory and the mean field theories, are briefly reviewed in this paper with the diagnosis of their advantages and limitations.
