潮土盐碱阳离子等温平衡吸附的数值模拟

Numerical Simulation of Isothermal Equilibrium Adsorption with Saline Ions in Fluvo-aquic Soil

采用4种常见的盐碱阳离子(Na+、K+、Ca2+、Mg2+)在潮土中进行等温静态批量平衡吸附实验,利用常见的4种平衡吸附方程分别进行拟合,进而得到各盐碱离子在土壤中的最佳等温吸附平衡方程,为预测黄淮海冲积平原地区盐碱离子的行为以及防止盐碱对该地区的威胁提供理论上的依据和指导。

In this paper, isothermal batch static equilibrium adsorption experiments of four common saline cations（Na^＋ ,K^＋ ,Ca^2＋ ,Mg^2＋） were conducted in Fluvo-aquic soil from Fengqiu, Four isothemal equilibrium adsorption equations were used to simulate the equilibrium adsorption, and then the optimal isothemal equilibrium adsorption equations for each saline cation were gained. The object of this research was provided some evidences for better predicting the saline ions behavior and prevented the threat from saline in HUANG-HUAI-HAI alluvial plain.
