The availability of commercial gravimetric and volumetric systems for the measurement of adsorption equilibrium has seen also a growth of the use of these instruments to measure adsorption kinetics. A review of publications from the past 20 years has been used to assess common practice in 180 cases. There are worrying trends observed, such as lack of information on the actual conditions used in the experiment and the fact that the analysis of the data is often based on models that do not apply to the experimental systems used. To provide guidance to users of these techniques this contribution is divided into two parts: a discussion of the appropriate models to describe diffusion in porous materials is presented for different gravimetric and volumetric systems, followed by a structured discussion of the main trends in common practice uncovered reviewing a large number of recent publications. We conclude with recommendations for best practice to avoid incorrect interpretation of these experiments.

用于测量吸附平衡的商业重量和体积系统的可用性也已经看到了使用这些仪器测量吸附动力学的增长。回顾了过去20年的出版物，以评估180例案件的惯常做法。观察到令人担忧的趋势，例如缺乏有关实验中使用的实际条件的信息，以及数据分析通常基于不适用于所用实验系统的模型这一事实。为了为这些技术的使用者提供指导，该贡献分为两个部分：针对不同重量和体积系统，讨论了描述多孔材料中扩散的适当模型的讨论，随后，通过对有组织的惯例的主要趋势进行了结构化的讨论，发现了大量近期出版物。我们以最佳实践的建议作为结尾，以避免对这些实验的错误解释。
