Description

General description

Amino-functionalized silica gel spherical is monodisperse in size and shape. It is prepared and characterized by thermogravimetery, X-ray diffraction, FT-IR, scanning electron microscopy (SEM) and N2 adsorption-desorption techniques.

Application

• Amino-Functionalized Silica@Resorcinol-Formaldehyde Nanocomposites for the Removal of Cr(VI) from Aqueous Solutions: This research presents the application of amino-functionalized silica gel spheres embedded in resorcinol-formaldehyde nanocomposites, specifically for environmental pollutant adsorption. The study focuses on the efficient removal of chromium (VI) from water, showcasing the material′s high adsorption capacity and potential for reusability. This application aligns well with the needs in environmental testing, particularly for labs focused on water purification and pollution control (Li, Lu & Zhu, 2023).
