Abstract:
: In this work, a hydrogel system was produced via radical polymerization of N,N-dimethylacrylamide and 2-acrylamido-2-methylpropanesulfonic acid in the presence of N,N-methylene-bis-acrylamide
as a crosslinker and ammonium persulfate as an initiator. Parameters that impact the conversion of
copolymerization (such as initial concentration of monomers, temperature, initiator dose, and time) were
studied. The swelling degree of the hydrogel was investigated with the addition of a crosslinker and
initiator at different pH levels. A hydrogel with high conversion and high swelling degree was selected
to investigate their ability for adsorption of Pb(II) ions from solutions. Adsorption behavior of Pb(II) ions
in a hydrogel was examined as a function of reaction time and concentration of lead ions from a solution
of Pb(II) ions.
