The mass percentage of nitrogen is reported in the lot-specific Certificate of Analysis. The minimum amount is 1%. As an example, a lot reporting a nitrogen content of 1.7% will have 1.7 grams of nitrogen per 100 grams of product. This value will allow for approximating the amount of NH bonding present in the material.

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.[1]
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).

amine functionalized 된 농도를 알고 싶습니다. bead 가 워낙 작으니까, 개당 amine 이 몇 mol 이 붙어있는지는 알기 힘들겠지만, g 당 amine 의 mol 농도를 알고자 문의드립니다. 감사합니다.
