MESOPOROUS ABSORBENTS TYPE M41S RESOLUTION RISE BY THE WAY OF CATION MODIFICATION - article

The possibility of usage of mesoporous materials’  M41S for the chromatographic separation of various organic combinations’ mixtures (that are divided into seven groups in accordance with their nature) is shown.

It has been established, that the modification of this adsorbents by cations of cadmium, tallium and silver increases their separating ability, which is calculated by the binar mixtures’ selectivity coefficients, by criterion of uniformity of multicomponent systems and effectiveness of chromatographic columns in the following sequence: MA< Cd – MA < Tl – MA < Ag – MA.
