Description A new alumina supported carbon composite material called “Eggshell Composite” (EC) was synthesized
from eggshell waste as calcium source for selective fluoride adsorption from water. The effect of various
synthesis parameters like eggshell (ES): Eggshell membrane (ESM) ratio, aluminium loading, mixing time
and calcinations temperature to optimize the synthesis conditions for selective fluoride removal has been
studied. It was observed that the synthesis parameters have significant influence on development of EC
and in turn on fluoride removal capacity. EC synthesized was characterized for elemental composition,
morphology, functionality and textural properties. Results showed that EC obtained from eggshell modified
with alumina precursor is more selective and efficient for fluoride removal. Langmuir and Freundlich
isotherm were used to obtain ultimate fluoride removal capacity. The calcium and alumina species in EC
shows synergistic effect in fluoride adsorption process. Fluoride sorption studies were carried out in synthetic,
groundwater and wastewater. EC proved to be a potential, indigenous and economic adsorbent
for fluoride removal.
