Abstract: Carbon spheres (CSs) were hydrothermally synthesized using sucrose as precursor. The synthesized CSs were activated with potassium hydroxide (KOH) until a substantial micropore structure was achieved. The surfaces of the microporous carbon spheres (MCSs) were further modified with amine groups at room temperature using 3-aminopropyltriethoxysilane (3-APTES). Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and Nitrogen Adsorption measurements were used to characterize the CSs, MCSs and the reaction product of MCSs with 3-APTES (3-APTES-MCSs). Results indicate the presence of Si-O-Si and -NH2 groups on the surfaces of the 3-APTES-MCSs. The surface modified product can be utilized as an adsorbent for the extraction of nitrogen-containing contaminants of emerging concern (CEC) from environmental samples.
Keywords: Microporous carbon spheres, hydrothermal reaction, 3-aminopropyltriethoxysilane, sucrose, surface modification.
