Abstract: Adsorption of methanol and ethanol over mesoporous
siliceous material are studied in the current paper. The pure
mesoporous silica is prepared using tetraethylorthosilicate (TEOS) as
silica source and dodecylamine as template at low pH. The prepared
material was characterized using nitrogen adsorption,nX-ray
diffraction (XRD) and scanning electron microscopy (SEM). The
adsorption kinetics of methanol and ethanol from aqueous solution
were studied over the prepared mesoporous silica material. The
percent removal of alcohol was calculated per unit mass of adsorbent
used. The 1st order model is found to be in agreement with both
adsorbates while the 2nd order model fit the adsorption of methanol
only.
