Understanding Adsorption: Theories, Techniques, and Applications
Marwah Ahmed Alsharif
Abstract
The chapter topic “Understanding Adsorption: Theories, Techniques, and Applications” will provide a comprehensive exploration of the fundamental theories, experimental techniques, and practical applications of adsorption processes. It will begin by discussing the foundational theories that explain adsorption behaviour, including physisorption and chemisorption, and their underlying molecular interactions. Key adsorption models, such as Langmuir, Freundlich and BET isotherms, will be reviewed to offer insights into adsorption dynamics, capacity and surface interactions. The chapter will also cover various experimental techniques used to characterise adsorption, such as gravimetric methods, gas adsorption analysis and calorimetry, which help determine the properties of adsorbents and adsorbates. Furthermore, the chapter will examine real-world applications of adsorption in diverse fields, including environmental engineering for water and air purification, gas separation, catalysis and energy storage systems. The potential of advanced adsorbent materials, such as porous materials and nanostructures, will be discussed in light of emerging challenges and technological advancements. This chapter aims to equip readers with both theoretical knowledge and practical insights into the wide-ranging applications of adsorption processes.
