摘要

Here we consider the routes of synthesis (which is performed by use of sol-gel method) of a new class of sorbents, namely: polysiloxane xerogels functionalized with nitrogen-, oxygen-, phosphorus- and sulfur content ligand groups. Applying a number of physical methods (SEM, TEM, AFM, IR and Raman spectroscopy, ~1H, ~(13)C, ~(29)Si and ~(31)P CP/MAS NMR, EPR spectroscopy, ERS, thermal analysis) we established the structure of both: the xerogels and their surface. An influence of some factors on the structural-adsorption characteristics of such xerogels and their sorption properties is analyzed.
