Abstract

Activated carbon (AC), the KOH modified activated carbon (KAC) and SBA-15 before and after pore expansion (SBA-15k) were modified using tetraethylenepentamine (TEPA) as modifier to synthesize the adsorbents. The adsorbents were characterized by N2 adsorption-desorption and elemental analysis. The results showed that the pore size of SBA-15 materials were much larger than that of activated carbon. SBA-15k (P)-40 had the largest pore size which was mainly in the range of 10~20 nm. KOH activation and SBA-15 reaming were beneficial to amino modification. In the same TEPA modification conditions, the actual TEPA loadings of SBA-15 materials were higher than those of activated carbons.
