Radiation Synthesis of Superabsorbent Hydrogel (Wheat Flour/Acrylamide) for Removal of Mercury and Lead Ions from Waste Solutions

The objective of this work is to prepare biodegradable hydrogel of wheat flour/acrylamide (F/AAm) using gamma radiation for the removal of Pb 2+ and Hg 2+ ions from waste solutions. Characterization of prepared (F/PAAm) hydrogel was carried out by FTIR, SEM, XRD and EDX. Factors affecting on the ads...

Description
Summary:The objective of this work is to prepare biodegradable hydrogel of wheat flour/acrylamide (F/AAm) using gamma radiation for the removal of Pb 2+ and Hg 2+ ions from waste solutions. Characterization of prepared (F/PAAm) hydrogel was carried out by FTIR, SEM, XRD and EDX. Factors affecting on the adsorption process such as pH of the medium, initial concentration, contact time and temperature were studied. The obtained hydrogel has highly swelling properties reached to over 9000 (%). The metal uptake of (F/PAAm) hydrogel for Pb 2+ and Hg 2+ were found to be 24.3 and 15.6 (mg/g), respectively. Kinetic and isotherm models were studied.
