Abstract:
Preparation of hybrid nanocompositional chitosan/silica sorbent was carried out. It was shown that formation of gel in sol-gel process of hydrolytic polycondensation of tetraethoxysilane (TEOS) with including of chitosan consists of two stages. Suppression of crystallization of chitosan in obtained two-phase system and changes in IR spectra are evidenced of interactions between molecules of chitosan and silanol groups of silica network. The resulting hybrid chitosan/silica sorbent was tested by high-performance liquid chromatography (HPLC).
