Preferred Label : ion exchanger;
IUPAC definition : A solid or liquid, inorganic or organic substance containing exchangeable ions with
others of the same charge, present in a solution in which the ion exchanger is considered
to be insoluble. It is recognized that there are cases where liquid exchangers are
employed and where it may be difficult to distinguish between the separation process
as belonging to ion exchange or liquid-liquid distribution, but the broad definition
given here is regarded as that which is most appropriate. A monofunctional ion exchanger
contains only one type of ionogenic group, a bifunctional ion exchanger two types
and a polyfunctional ion exchanger more than one type. In a macroporous ion exchanger
the pores are large compared to atomic dimensions.;
