摘要

The adsorbents (polysiloxane xerogel, silicagel Davisil, mesoporous silica SBA-15) containing macroligands, such as calix[4]arenes, diaminodibenzo-18-crown-6-ethers, a- and P-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~+ (~(137)Cs) and Na~+, K~+, Sr~(2+) (~(90)Sr), and organic compounds of different kind, has been investigated.
