ontamination of drinking water due to fluoride is a severe health hazard
problem. Excess of fluoride (>1.5 mg/L) in drinking water is harmful to
human health. Various treatment technologies for removing fluoride from
groundwater have been investigated. The present study showed that the
leaves of
Moringa oleifera
, an herbal plant are an effective adsorbent for the
removal of fluoride from aqueous solution. Acid treated
Moringa oleifera
leaves
powder showed good adsorption capacity than alkali treated
Moringa oleifera
leaves powder. Batch sorptive defluoridation was conducted under variable
experimental condition such as pH, contact time, adsorbent dose and initial
fluoride ion concentration. Maximum defluoridation was achieved at pH 1. The
percentage of fluoride removal increases with adsorbent dose. The equilibrium
sorption data were fitted into Langmuir, Freundlich and Temkin isotherms. Of
the three adsorption isotherms, the R
2
value of Langmuir isotherm model was
the highest. The maximummonolayer coverage (Q
max
) from Langmuir isotherm
model was determined to be 1.1441 mg/g, the separation factor indicating
a favourable sorption experiment is 0.035. It was also discovered that the
adsorption did not conform to the Freundlich adsorption isotherm. The heat
of sorption process was estimated from Temkin isotherm model to be -0.042
J/mol which vividly proved that the adsorption experiment followed a physical
process

Shabnam Dan is a Research Scholar in the Department of
Chemistry at Sam Higginbottom University of Agriculture,
Technology and Sciences, Allahabad, India. Currently, she
is working on Nanoadsorbents, trying to incorporate a few
aspects of polymer chemistry. Her research interest lies in
the area of surface chemistry especially adsorption. She has
a good research aptitude. Her past research works focuses
on defluoridation using chemically modified biosorbent,under
which she has two research publications, one of which is
published in a Springer journal of high repute. She also has an
experience of teaching as a Guest Lecturer in Department of
Chemistry, Ewing Christian College which is one of the oldest
and good colleges of the city. She is also serving as a Reviewer
in one of the Springer journal and has also been invited by a
journal to be a part of the Editorial Board.
