Swelling studies and adsorption of safranin T by acrylamide/maleic acid/methylene-bis-acrylamide based hydrogels

Swelling studies of an acrylamide/maleic acid/methylene-bis-acrylamidebased hydrogel prepared by free radical polymerization (weight ratio of 90/10/3) are presented. Water penetration mechanism was studied by using two classical definitions, i.e., Crank (FC = W /W ) and Karadag (FK = (W -W )/W ), of...

Description
Summary:Swelling studies of an acrylamide/maleic acid/methylene-bis-acrylamidebased hydrogel prepared by free radical polymerization (weight ratio of 90/10/3) are presented. Water penetration mechanism was studied by using two classical definitions, i.e., Crank (FC = W /W ) and Karadag (FK = (W -W )/W ), of the water fraction into the hydrogel (F). An anomalous water penetration mechanism (0.5
