等温线模型对平衡数据的定量描述是吸附研究中不可缺少的环节。以前的综述论文侧重于基本假设，拟合方法,等温线模型的误差函数和实际应用，通常忽略它们的曲线特征，选择标准和常见争议。本综述的主要内容包括：（i）模型参数对等温线曲线的影响；（ii）确定站点能量分布；（iii）等温线模型的选择标准；（iv）消除一些常见的争议。揭示曲线特性对于选择合适的等温线模型具有重要意义。位点能量分布有助于了解吸附剂表面的物理化学性质。建议将完整的等温线与实验数据相关联。应谨慎采用模型参数qmax来比较吸附剂性能。残差图可用于进一步诊断等温线模型的拟合质量。这篇评论还解决了一些常见的错误和争议，从而避免了它们在未来出版物中的传播。
The quantitative description of the equilibrium data by the isotherm models is an indispensable link in adsorption studies. The previous
review papers focus on the underlying assumptions, fitting methods, error functions and practical applications of the isotherm models, usually ignoring their curve characteristics, selection criteria and common controversies. The main contents of this
review include: (i) effect of the model parameters on the isotherm curves; (ii) determination of the site energy distribution; (iii) selection criteria of the isotherm models; and (iv) elimination of some common controversies. It is of great significance to reveal the curve characteristics for selecting a proper isotherm model. The site energy distribution is conducive to understanding the physicochemical properties of the adsorbent surface. The complete isotherm is recommended to be correlated with the experimental data. The model parameter qmax should be cautiously adopted for comparison of the adsorbent performance. The residual plot can be used to diagnose the fitting quality of the isotherm models further. This
review also addresses some common mistakes and controversies and thereby avoids their propagation in future publications.
