Properties, ion-exchange behavior, and analytical applications of cerium phosphate cation exchangers suitable for column use

Some investigations on the preparative procedure of cerium phosphate cation exchangers suitable for column use are reported. A number of novel forms o f cerium phosphate compounds in the presence of different salts are synthes ized. The properties of these inorganic ion exchangers have been characteri zed on the basis of chemical analysis, UV, thermal, IR and x-ray diffractio n methods. Their ion-exchange properties, chemical stability, and selectivi ty for certain ions are investigated.
