Popis:	On the basis of an analysis of published data, it is suggested that the affinity of cations for a silica surface should be determined not only by electrostatic forces but also by the nature of the electron density distribution between the silicon atoms and the metal ion in the surface M+ SiO− groups. This suggestion was tested and qualitatively confirmed by experiments on the sorption of cations of the elements of the main subgroups I–III of the periodic system on the calcium (from solutions of the nitrates) and hydrogen (from solutions of the hydroxides) forms of silica gel, and also by the results of a study of the infrared spectra of a number of cation-substituted forms of this sorbent in the range 700–1500 cm−1.
