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