This book was released on 2013 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the thermodynamic parameters of the adsorption of dyes specially methylene blue (MB) on different low-cost adsorbents. The comparison of enthalpy change ( H ) and entropy change ( S ) clearly divides the adsorbents into two groups, namely, inert or inorganic and natural or lignocellulosic adsorbents. The former group follows the van't Hoff equation and no compensation effect is required in the computation of enthalpy and entropy changes. On the other hand the second group requires the consideration of compensation effect which is generally overlooked by almost all of the authors. Although the calorimetry is the best solution to get the reliable values of thermodynamic parameters in almost all systems, a quick estimate is generally obtained from the equilibrium constant especially in adsorption studies. It might be acceptable in inorganic adsorbents due to low compensation temperature but it would be more erroneous in lignocellulosic adsorbents hence their contribution need be accounted for to get more reliable results."

Available in PDF, EPUB and Kindle. Book excerpt: Adsorption technology is a promising avenue for wastewater treatment. Numerous adsorbent materials are presently synthesized. Green or environmental friendly adsorbents are derived from plants and agricultural crop sources, giving them a very low production cost when compared to synthetic polymers. This monograph explains the basic principles of green adsorption technology, their production processes and strategies to remove different categories of environmental pollutants (dyes, heavy metals and phenols/pesticides). The book explains details in terms of features such as adsorption capacity, physico-chemical kinetics and reuse potential. A summary of the economics and future prospect for green adsorption technology is also given. This text is a handy reference for environmental chemistry students, researchers and policy makers.

Available in PDF, EPUB and Kindle. Book excerpt: The book is concerned with the main assumptions of the theory of Gibbs capillarity theory and fundamental thermodynamic equations, derived by the method of the finite thickness layer. Special attention is given to applied aspects of the thermodynamic theory of surface phenomena. Methods for calculating adsorption in multicomponent solutions are examined in detail. Systems of equations for calculating adsorption in real multicomponent systems from the concentration dependence of surface tension are derived for the first time. Experimental data on surface tension and density in binary and multicomponent systems are presented. Analysis of the results is used to develop methods for predicting the surface properties of multicomponent systems from the data on the properties of binary melts.

Download or read book Physical Adsorption written by L.W. Bruch and published by Courier Dover Publications. This book was released on 2007-03-29 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive account of the phenomena that occur when simple gases interact with surfaces, this text takes a fundamental perspective. Physical adsorption involves atomic or molecular films bound to surfaces by less than 0.5 eV per particle. Physically absorbed thin films exhibit remarkably diverse properties and behave in a manner characteristic of two-dimensional matter. This exploration focuses on monolayer physics, emphasizing atomic rather than molecular adsorption. The phase diagrams of physically absorbed films are diverse and rich in structure because of the subtle and varied competition between the two interactions: the mutual interaction between adsorbed molecules, and the force binding each molecule to the surface. The authors explain the microscopic origin of these forces in terms of constituent electrons and nuclei. They then examine the structural and dynamical properties of these films in the context of atomic and solid-state physics, statistical mechanics, and computer simulations. This text will be of interest to research chemists, physicists, and engineers alike, as well as students in these fields. Key literature citations allow readers to trace important developments, and thought-provoking problems are addressed in detail.

Fundamental equilibria and kinetics are dealt with for homogeneous as well as heterogeneous particles. Five chapters of the book deal with equilibria and eight chapters deal with kinetics. Single component as well as multicomponent systems are discussed. In kinetics analysis, we deal with the various mass transport processes and their interactions inside a porous particle. Conventional approaches as well as the new approach using Maxwell-Stefan equations are presented. Various methods to measure diffusivity, such as the Differential Adsorption Bed (DAB), the time lag, the diffusion cell, chromatography, and the batch adsorber methods are also covered by the book. It can be used by lecturers and engineers who wish to carry out research in adsorption. A number of programming codes written in MatLab language are included so that readers can use them directly to better understand the behavior of single and multicomponent adsorption systems.
Download or read book Adsorption From Solution written by R. H. Ottewill and published by Elsevier. This book was released on 2012-12-02 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adsorption From Solution discusses the significance of adsorption behavior in thermodynamic terms, with emphasis on the interplay between enthalpic and entropic contributions to the free energy. This book examines the role of simple models and of elementary thermodynamic and statistical mechanical arguments in relation to the concept of surface phase. Organized into 22 chapters, this book starts with an overview of the theoretical model for the solid/liquid interface. This text then proceeds with a discussion of the general thermodynamic treatment of adsorption from mixed solvents, which is designed to apply in situations where adsorbed species may be regarded as distinct from their bulk counterparts. Other chapters discuss the adsorption from solutions of various interfaces of liquid/gas, liquid/liquid, or liquid/solid. The final chapter deals with the roles of adsorption from solution in controlling other phenomena, such as liquid–liquid displacement, wetting, and the forces between colloidal particles. Physicists, chemists, and materials scientists will find this book extremely useful.
