Adsorption by Powders and Porous Solids (eBook, ePUB)

Principles, Methodology and Applications

• Format: ePub

Produktbeschreibung

The declared objective of this book is to provide an introductory review of the various theoretical and practical aspects of adsorption by powders and porous solids with particular reference to materials of technological importance. The 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, a critical account is given of recent work on the adsorptive properties of activated carbons, oxides, clays and zeolites. - Provides a comprehensive treatment of adsorption at both the gas/solid interface and the liquid/solid interface - Includes chapters dealing with experimental methodology and the interpretation of adsorption data obtained with porous oxides, carbons and zeolites - Techniques capture the importance of heterogeneous catalysis, chemical engineering and the production of pigments, cements, agrochemicals, and pharmaceuticals

Rezensionen

"An introductory chapter summarizes relevance, history, and terminology of adsorption, including chemisorption vs. physisorption, and discusses energetics, molecular modeling, and diffusion. The following chapters treat thermodynamics at a gas/solid and solid/liquid interfaces, measurement and monitoring technique, isotherm theory and interpretation, mathematical modeling of adsorption processes, and use of adsorption to measure surface area and porosity of materials." --ProtoView.com, January 2014

Review of first edition:
"A long-awaited but worthy successor to the book considered by many to be the bible of porous materials characterization: 'Gregg & Sing' (2nd Edition, 1982). This collaboration between the Rouquerols and Ken Sing has created a detailed handbook covering not only important theoretical aspects, but copious experimental and application information too. Adsorption calorimetry gets more attention than before (not surprising given the Rouquerols' affiliation), as do 'new' materials such as MCM's and 'new' calculation models like DFT (Density Functional Theory) and Monte Carlo simulation. Importantly, there is a great deal of coverage given to adsorptives other than nitrogen (the most common but not necessarily the most appropriate in all cases). Hundreds of references are given for follow-up reading in areas of special interest. Anyone seeking a reliable, broad, yet highly informative coverage of adsorption methodology for porous materials characterization should invest in this title." --Worthy Successor by "thomasetc" (USA), June 2000, Amazon.com
