Abstract:

The hybrid materials based on polysiloxane modified by amino groups have been synthesized by the sol-gel method. Aminated polysiloxane has been prepared by the copolycondensation reaction of tetraethoxysilane with gamma-aminopropyltriethoxysilane (APS-1) and through the modification of the product (APS-2) of the hydrolysis of tetraethoxysilane by gamma-aminopropyltriethoxysilane. The composition of sorbents has been confirmed by the elemental analysis and IR Fourier spectroscopy. The high degree of sorption extraction of copper(II), nickel(II), cobalt(II), zinc(II), cadmium(II), and lead(II) ions in the case of their coexistence in an ammonia-acetate buffer solution has been observed for polysiloxanes APS-2. The synthesized surface-modified materials exhibit the highest selectivity to nickel(II) and cobalt(II) ions.
