Abstract: Chromatog. of 24 metal ions was studied on silica gel layers, impregnated with tri-Bu phosphate. Aq. solns. of LiCl, NaBr, and NaI were used as mobile phases. RF values are summarized as a function of the concn. of the mobile phase. On some examples, the linear dependence of RM = log[(1/RF) - 1] on log [mobile phase concn.] is demonstrated. An extn. mechanism, and not ion exchange, is responsible for the chromatog. of the ions. Examples of sepn. of mixts. contg. 3-6 metal ions are given.
