Preparation and post-treatments of ordered mesoporous carbons (OMC) for resorcinol removal
Ren, H.; Shou, W.; Ren, C. & Gang, D. D.
Abstract
In this investigation, acrylic acid was used as a
carbon precursor and SBA-15 as a mesoporous template to
synthesize the ordered mesoporous carbons (OMC). Different
ratios of SBA-15 to acrylic acid were evaluated to
improve the OMCs adsorption capacity. It was found that
the optimal ratio of SBA-15 to acrylic acid is 3:1. In the
post-treatment study, four methods (NaOH, urea, NH3H2O,
and AlCl3) were explored to investigate their influences on
resorcinol removal. Results showed the ammonium
hydroxide-treated OMC had the highest adsorption capacity
of 40.6 mg/g for resorcinol removal. The nano-structures of
the OMC and post-treated OMCs were characterized and
confirmed. FTIR analysis indicated that the surface functional
groups were changed after post-treatments. XRD
patterns and TEM images suggested that the ordered
structure was well maintained during the post-treatment
processes, although the erosion effect was observed.
