✦ Synopsis

The liquid ion exchanger investigated, Alamine 33G, may be used to effect numerous separations of metal ions in thiocyanate media. Some separations have been quantitatively demonstrated while others are suggested by the analogous behavior of metal ions in their particular extraction group. Under the mild conditions used in this study, i.e. room temperattire and pressure, 1o-3o~/~ (v/v) solution of exchanger in toluene, thiocyanate and acid concentrations less than 1.0 M, the physical handling of the amine was no problem. Phase separations were quick and clean for the solvent extraction work and there was no problem of extractant bleeding from the support in the reversed-phase column work.

## Abstract The retention behavior of inorganic anions on a triazole‐based stationary phase was first examined in ion chromatography. It was initially designed for hydrophilic interaction liquid chromatography and was simply prepared by introducing the triazole groups onto the surface of silica gel
