This chapter reviews some interesting aspects of the use of ion-exchange methodologies. Ion-exchange resins are useful in industry for research aimed at improving the quality of several biorefinery processes. The chapter describes different types of resins that may be classified as strong acid cation resins, weak acid cation resins, strong base anion resins and weak base anion resins. The chapter also provides an extensive review of commercial applications ranging from softening water to biodiesel purification. In recent years, ion-exchange resins have been used in membrane processes. New approaches to the use of ion-exchange resins should focus on the production of more efficient resins and a wider range of applications in order to be more competitive with membrane systems.
