ABSTRACT
Fluoride contamination in potable water and ground water streams due to natural and anthropogenic activities
has been known as one of the key problems worldwide imposing a serious threat to human health. Amongst the
various treatment methods available for fluoride removal, adsorption process is regarded as efficient and
practical. A general list of various inorganic, organic and natural adsorbents from literature has been compiled
and discussed. The effects of different parameters such as pH, initial fluoride concentration, temperature,
contact time, adsorbent surface charge, etc. were also discussed. This review paper incudes the entire spectrum
of adsorbents used for defl uoridation, factors affecting adsorptive defl uoridation process, and also discussed
the isotherms and kinetics used for the data interpretation.
