Abstract

This research aims to tackle the issue of increasing harmful pollutants in the environment by creating monodispersed silica hybrids, namely vinyl ormosil (VO) and phenyl ormosil (PO), and assessing their effectiveness as phenol adsorbents in aqueous solutions. To comprehend the correlation between structural attributes and functionality, such hybrid materials are analyzed based on surface and bulk properties. Attaining monodispersity, a defining characteristic of ormosils, is a crucial element in the synthesis process, requiring meticulous scrutiny of several factors. The ATR-FTIR spectra of the monodispersed silica hybrids display distinct characteristics, notably a decrease in Si–O-Si linkages. The formation of Si–O-Si bonds in silica hybrids is due to cross-linking, leading to two distinct peaks at 1050 cm⁻1 and 1149 cm⁻1, which correspond to Si–O and Si–C fragments, respectively. It was evident the synthesized adsorbents monodispersed silica ormosils VO and PO were efficient enough to remove 90% of nitrophenol and aminophenol. It suggested that the saturation or unsaturation of the organic moiety with conjugation influenced binding efficacy. This study enhances comprehension of the design and utilization of nanostructured materials for environmental remediation.
