Application of ultrasound and methanol for rapid removal of surfactant from MCM-41
Ultrasound waves have been successfully applied for removing template from the mesoporous MCM-41 molecular sieve. The method uses a 28 KHz ultrasound irradiation in a methanol solvent for disrupting micellar aggregation of the surfactant molecules, cetyltrimethylammonium bromide, which have...

| description | Ultrasound waves have been successfully applied for removing template from
the mesoporous MCM-41 molecular sieve. The method uses a 28 KHz ultrasound
irradiation in a methanol solvent for disrupting micellar aggregation of the
surfactant molecules, cetyltrimethylammonium bromide, which have filled the
pores of the as-synthesized MCM-41. In 15 min sonication at moderate
temperature of 40 °C, a majority of surfactant molecules are removed out
from powder MCM-41. The template removal rate using ultrasound irradiation
(15 min) is faster than the rate via thermal calcination and a perfect
hexagonal pore structure was obtained after the template removal using
ultrasound irradiation, according to the characterization using the X-ray
diffraction (XRD), and nitrogen adsorption analyses, while high temperatures
in calcination will cause shrinkage which is affected on the surface
properties of materials. In this procedure, the surfactant molecules are
released into methanol and can be recovered for reuse. The effectiveness of
the sonicated prepared MCM-41 as an adsorbent has been confirmed using the
adsorption reaction with Methylene Blue (MB). |
