generated by nuclear power plants. The bio-
sorption is one the most effective technique
to eliminate cations from aqueous solution.
This procedure has the advantage to remove
the metals in low concentration by means of
renewable sources. The removal efficiency of
strontium ions by raw and treated coconut fi-
bers was assessed and reached up to 45 and
95% respectively in an aqueous solution.
