Thin4ayer chromatography has been performed on plates spread with polystyrene-imminodiacetate-ex-changer (Chelex 100) bound to the ammonia complexes of different metal ions such as nickel(II), zinc(II), copper(II) and cobalt(Ill). A ligand.exchange effect was evidenced in the separation of some diamines, u-amino acids and carboxylic acids. The method may be used for the analysis of very dilute solutions and as a useful test of the best operating conditions for column chromatography.

Abstract
Thin4ayer chromatography has been performed on plates spread with polystyrene-imminodiacetate-ex-changer (Chelex 100) bound to the ammonia complexes of different metal ions such as nickel(II), zinc(II), copper(II) and cobalt(Ill). A ligand.exchange effect was evidenced in the separation of some diamines, u-amino acids and carboxylic acids. The method may be used for the analysis of very dilute solutions and as a useful test of the best operating conditions for column chromatography.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
