Preparation and Heavy Metal Ions Chelating Properties of Multifunctional Polymer-Grafted Silica Hybrid Materials

<div>FTIR spectra of silica (SiO<sub>2</sub>), aminated silica (Si<i>γ</i>), linear polymers ([BAC-DMEDA], [BAC-EDDA]), and polymer-grafted materials (Si<i>γ</i>-[BAC-DMEDA], Si<i>γ</i>-[BAC-EDDA]). Inset shows the amplified spectra of silica (SiO<sub>2</sub>) and aminated silica (Si<i>γ</i>) within the wavenumber region of 4000 and 1700 cm<sup>−1</sup>.</div>
