Abstract:
Synthetic ion exchangers are used for a wide range of different applications, ranging from water softening, water remediation, catalysis, molecular sieving, and selective adsorption to medical applications. Their well-defined compositions and tunable structural features allow minute tailoring of their specific properties. A selection of the most prominent ion exchangers for aqueous ion exchange is introduced in this chapter, and the ion exchange process is illustrated for selected materials. Furthermore, structural features of individual materials are discussed and typical preparation methods and applications are addressed.
