Abstract
This chapter first reviews the basic theory underlying adsorption-based methods. It then highlights some key issues, beyond what is normally found in apparatus manuals, which arise when conducting experiments. The particular reasons for the choice of adsorbate to characterise a given adsorbent are then discussed. The types of data that can be obtained from various types of sorption experiments are then described, along with suggestions for several different data analysis methods to deliver a range of descriptors for porous solids. These include surface area, pore sizes, surface roughness, pore connectivity, pore length, and degree of spatial heterogeneity.
