| dc.description.abstract | Abstract:
In this paper
results obtained on the kinetics of este
r adsorption on raw, acid treated and pre
-
heated
bentonite have bee
n presented. T
he infra
-
red profiles and the XRF spectra of the raw and
acid activated
bentonite have also been discussed.
The change in properties of bentonite on heating and acidification
are shown to affect its adsorption
characteristics. The adsorption efficiencies of bentonite are high, enhanced on acidification but diminished with
pre
-
heating.
Infra
-
red spectra shows that the C=O stretching vibration of the adsorbed molecules shifted to
lower
frequencies compared with the carbonyl band at 1700cm

in the spectra of pure esters. The Lewis and
Bronsted acid sites on the raw and acidified bentonite samples were also identified from the spectra of ethyl
acetate adsorbed on the raw and acidi
fied samples.
Quantitative elemental analysis of the raw and acid treated bentonite shows changes in the amounts of
cations on acidification | en_US |
