Abstract:

A series of gamma-aminopropylsilylated sorbents was obtained from different oxide supports (silica gels, silica fillers, macroporous glasses, alumina) and by the direct synthesis (hydrolytic polycondensation of tetraalkoxvsi lanes with gamma-aminopropyltriethoxysilane). The highest degree of immobilization was achieved for silicas, while the most convenient solvent was methanol. Sorbents with beta-alanine functional groups were obtained by the subsequent reaction with acrylic acid. The degree of beta-carboxyethylation was 1.3-1.9, and the highest content of functional groups (nu(COOH) = 3.23 mmol g(-1)) was achieved for carboxyethylated xero gel synthesized by the copolycondensation of tetraethoxvsilane with gamma-aminopropyltriethoxysilane. The sorbents containing beta-alanine possess a higher selectivity of Cu2+ ion sorption than the initial gamma-aminopropylsitylated sorbents.
