Abstract

Hybrid hydrogel networks synthesized by the simple free radical polymerization of acrylamide,
acrylamidoglycolic acid and cloisite sodium clay. To synthesize these hybrid hydrogels N,N’-
methylenebisacrylamide used as a cross linker and ammonium peroxydisulphate used as an initiator. The
structural characterization of this poly(acrylamide-co-acrylamidoglycolic acid/cloisite hybrid hydrogels
(PAAGC), were done using Fourier transform infrared spectroscopy. The resulting hybrid networks was used as
an adsorbent for studying the effectiveness in the removal of methylene blue (MB), which is having a wide range
of use in different fields such as biology and chemistry. The effects of contact time, initial sorbate concentration,
pH, and dose of adsorbent were studied to optimize the adsorption capacity. The batch sorption technique
employed, revealed a maximum adsorption. Adsorption isotherms and Kinetic models were fitted to know the
adsorption mechanism. This Hybrid hydrogels exhibited excellent performance in MB adsorption. The
investigations demonstrated that the PAAGC can be based as an efficient adsorbent for the removal of MB from
aqueous solution.
