Abstract:
Salicylaldehyde Schiff base of amino-methylated
polystyrene has been developed as a novel reagent for the removal
of Fe(III) from solutions. The selectivity of the metal
ion uptake over a wide range of different concentrations of
metal ion, effect of pH, ligand concentration and the influence
of other foreign ions were studied. A very good selectivity
was achieved for the removal of the ion. It was found
that 0.01 g of the ligand was sufficient to achieve about 96%
removal of the metal ion in terms of concentration (ppm)
from a 30 ppm solution in acidic pH.
