Ion exchange is a reversible interchange of one species of ion present in an insoluble solid with another of like charge present in a solution surrounding...

An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. It is an insoluble...

Ion chromatography (or ion-exchange chromatography) is a form of chromatography that separates ions and ionizable polar molecules based on their affinity...

An ion-exchange membrane is a semi-permeable membrane that transports certain dissolved ions, while blocking other ions or neutral molecules. Ion-exchange...

Glass membranes are made from an ion-exchange (absorption of ions of interest occurs, if it were simple ion exchange no charge would be generated) type...

Anion-exchange chromatography is a process that separates substances based on their charges using an ion-exchange resin containing positively charged...

additional ion is often a hydrogen ion; for ion exchange mechanisms, the distribution ratio is often a function of pH. An example of an ion exchange extraction...

Nicotine polacrilex is nicotine bound to an ion-exchange resin (polymethacrylic acid, such as Amberlite IRP64, Purolite C115HMR or Doshion P551). It is...

hydrochloric acid is used in the regeneration of ion exchange resins. Cation exchange is widely used to remove ions such as Na+ and Ca2+ from aqueous solutions...

H+ and Na+ can be replaced by diverse cations, because zeolites have ion exchange properties. The nature of the cations influences the porosity of zeolites...
