Summary
Summary
This overview of diffusion and separation processes brings unsurpassed, engaging clarity to this complex topic. Diffusion is a key part of the undergraduate chemical engineering curriculum and at the core of understanding chemical purification and reaction engineering. This spontaneous mixing process is also central to our daily lives, with importance in phenomena as diverse as the dispersal of pollutants to digestion in the small intestine. For students, Diffusion goes from the basics of mass transfer and diffusion itself, with strong support through worked examples and a range of student questions. It also takes the reader right through to the cutting edge of our understanding, and the new examples in this third edition will appeal to professional scientists and engineers. Retaining the trademark enthusiastic style, the broad coverage now extends to biology and medicine.

Choice Review
This second edition (1st ed., CH, Dec'84) of a successful book retains the elegant and clear description of the basic diffusion mechanism and the equations that model it. However, material on mass transfer and a wide range of processes dependent on it have been added. Thus, this new edition is larger and more oriented toward engineering than was the first. The fundamental material, some 40 percent of the book, deals with diffusion in dilute and concentrated solutions, dispersion, diffusion coefficients, diffusion with reaction, and multicomponent diffusion. Following a chapter on mass transfer are 12 chapters on processes in which mass transfer and diffusion are central--absorption, distillation, extraction, adsorption, forced and free convection, heterogeneous and homogeneous chemical reactions, membranes, controlled release phenomena, heat transfer and simultaneous heat and mass transfer are all discussed. These chapters expose the process mechanism and the role of mass transfer in the process rather than arriving at design procedures. Throughout, the writing is crisp, making the material fresh and interesting. A student reading this book will obtain a clear understanding of the mechanism and equations of diffusion and an appreciation of its role in a wide range of physical processes. Upper-division undergraduate and graduate students. L. A. Wenzel; Lehigh University
