Factors Influencing the Adsorption Properties of Silicas Functionalized by Macrocyclic Ligands

Conference paper
Part of the NATO Science for Peace and Security Series C: Environmental Security book series (NAPSC)

Abstract

The adsorbents (polysiloxane xerogel, silicagel Davisil, mesoporous silica SBA-15) containing macroligands, such as calix[4]arenes, diaminodibenzo-18-crown-6-ethers, α- and β-cyclodextrins, have been obtained by the sol-gel method and the surface modification method. The influence of the synthesis conditions, the nature of macrocyclic compounds and routes of their grafting on the structural-adsorption characteristics of the obtained polysiloxane materials and their sorption properties toward Cs+ (137Cs) and Na+, K+, Sr2+ (90Sr), and organic compounds of different kind, has been investigated.
