Adsorption by Powders and Porous Solids: Principles, Methodology, and Applications, Third Edition provides a comprehensive treatment of all aspects of adsorption at both the gas/solid interface and the liquid/solid interface, while also covering the application aspects of adsorption. The book gives an introductory review of the various theoretical and practical aspects of adsorption by powders and porous solids with reference to advanced techniques and applications (including separation of industrial gases and pollution control, catalysis, gas storage) involving materials of technological importance. It is primarily written for advanced undergraduates, postgraduates, lecturers, researchers, and practitioners in physical chemistry, materials science, surface science, and chemical engineering. The book's primary aim is to meet the needs of students and non-specialists who are new to surface science or who wish to use the advanced techniques now available for the determination of surface area, pore size and surface characterization. In addition, for this fully updated third edition, a critical account is given of the most recent work on the adsorptive properties of activated carbons, oxides, clays, zeolites, and MOF's.
