Abstract :
Fe(II)-loaded pectin based hydrogels were used to remove As(V) from water. The hydrogels were synthesized by crosslinking pectin ‘as such’ or in the presence of 2-acrylamido-2-methylpropanesulphonic acid and three crosslinkers. The hydrogels crosslinked with 5% glutaraldehyde showed the maximum uptake of both Fe(II) and As(V). The sorption of As(V) was found to be sensitive to pH and temperature changes, as the maximum sorption was observed at 35 °C and 7.0–9.2 pH.
