ABSTRACT. The new approach to enhancing the selectivity of sorption separation of metal ions was suggested. The approach is based on using mixed sorbents, which may be obtained, e.g. by simultaneous immobilization of complexing reagents on silica gel and reverse-phase silica gel (C 16, Ph). The methods are developed for the simultaneous determination of two (Co-Fe, Co-Zn, Al-Mn) or three (Al, Mn, and Fe) elements with the performance of 21-36 samples per hour.
