The latest volume in the series, Volume 18 reflects the diversity in the field of ion exchange with a wide range of topics that impact catalysis, synthesis, molecular imprinting, green processes, drug delivery, nanotechnology, water treatment, and environmental pollution-control. Topics include: solvent sorption equilibria and kinetics of ion exchange resins, synthesis applications for cation exchange resins, drug delivery and other novel applications of ion exchange resins, the use of biopolymers as catalyst supports, predicting relative permeability of different ions in RO and NF processes, applications of chitosan in the separation and purification of metal ions, and advantages of short-bed units.
