Annotation Reflecting the sustained and diverse experimental momentum in the field of ion exchange, Volume 16 summarizes revolutionary advances on par with the consistently high-level research related by this series. This text discusses the kinetics, theoretical models, experimental results/supporting data, and applications for isothermal supersaturation, metal separation via pH-induced parametric pumping, and for ultrapure water (UPW). Topics also include the engineering of activated carbons and carbonaceous materials for removal of metal ions; hydrophobic ionizable organic compounds (HIOCs); the sorption/desorption mechanisms of organic micropollutants in water; and ion exchange process variables on perchlorate treatment.
