The Principles of Ion Exchange Technology covers the fundamental properties of ion exchange resins and the chemical engineering principles of plant design to aid process and equipment evaluation, choice and design.

This text is composed of 12 chapters and begins with a discussion of the equilibrium concept and the calculation of diffusion coefficients and mass transfer coefficients, as well as the rate constants in ion exchange. The succeeding chapters deal with the kinetics of ion exchange in solution and in resin beads. These topics are followed by reviews of axial mixing, flow abnormalities, design equations, fixed bed performance calculation, and multi-component ion exchange. The final chapters explore the choices of continuous and countercurrent design techniques and the practical procedures for packed beds.

This book is of great value to chemical engineers.
