Abstract

For investigation of a surface layer structures of silica gels with the different pore size, modified
by monoethanolamine and as interactions of the superficial structures with water solutions of calcium
ions both metalloindicators calmagite and arsenazo I are used IR-spectroscopy and potentiometric
titration methods. It is positioned, that monoethanolamine molecules covalently contact a surface of silica
gels with formation of ester groups Si-O-C. Received surface aminoethoxy groups possess properties of
mild base and are capable to create рН = 9 in aqueous slurries of the modified silica gels
