摘要
为了实现对吸附反应的平衡吸附量的预测,建立了平衡吸附量预测模型.以高岭土、蒙脱土这两种黏土矿物吸附Ca2+为例,验证其等温吸附曲线符合Langmuir吸附方程.在Langmuir吸附等温式的基础上,建立了平衡吸附量预测模型,该模型应用于单组分吸附反应的平衡吸附量的预测.通过实验对该模型进行了验证,模型的计算结果与实验结果可以较好地吻合,证明该模型的可靠性较高.
A model was developed to predict equilibrium adsorption amount in an adsorption reaction.The adsorption isotherm of kaolinite and montmorillonite adsorbing Ca2＋ followed the Langmuir adsorption equation.Based on the Langmuir isothermal adsorption equation,a model was developed that is able to predict the equilibrium adsorption of single component adsorption reactions.Results calculated by the prediction model coincided with experimental results,indicating good reliability of the prediction model.
