| Abstract: | The elution behavior of 4 amines, ethanolamine, diethanolanine, dimethylamine and n-butylamine, was studied on 4 cation-exchange resins and zirconium phosphate, all loaded with nickel ions. Aqueous ammonia was used for clution. Different selectivity orders were found with exchangers of different types. The carboxylic cation-exchange resin gave the sharpest bands, but 2% cross-linked sulfonic resin gave the best separation of these amines. |
