Title: STUDIES ON MODIFIED HYDROGELS OF ACRYLAMIDE COPOLYMERISED WITH NATURAL RESOURCES
Authors: DWIVEDI, DEVENDRA PRATAP
Keywords: Hydrogels
Series/Report no.: TD-900;
Abstract: Hydrogels were prepared by copolymerisation of Acrylamide with natural resources ; (1) Cane sugar juice (2) Sapodilla (chikoo- Manilkara zapota) extract (3) Pineapple( Ananas comosus) juice with the help of initiator [(Potassium Peroxydisulphate).(KPS-K2S2O8)]and using N,N'- Methylenebisacrylamide ( N,N-MBAAm) as crosslinking material in aqueous medium. Hydrogels of homopolymer of acrylamide and its copolymers with acrylic acid and methacrylic acid were also prepared for the purpose of comparision of results obtained. These hydrogels were characterised by FTIR ,SEM and XRD analysis . Swelling study of the above hydrogels were performed in aqueous media as a function of time. Stimuli response of pH of medium and temperature on swelling were also studied . Hydrogels were used for sorption study of hazardous metal ions [ Hg(II) , Pb(II) , Cd(II) ] as a function of Time , pH and temperature .
