Synthesis of Methacrylamide/Chitosan Polymeric Cryogels and Swelling/Dye Sorption Properties

In this study, polymeric cryogels were synthesized to develop a new methacrylamide-based polymeric material that includes chitosan to remove dyes that may be present as contaminants in aqueous media. Methacrylamide/chitosan (MAmCS) cryogels prepared under cryogenic conditions were characterized by FTIR, SEM/EDX and swelling tests. It was determined that the Langmuir isotherm model, pseudo second order and intra-particle kinetic models were found to be the best fit models to describe adsorption between polymeric cryogels and anionic dye calconcarboxylic acid (CCA). The results showed that the cryogels obtained can be used as an alternative adsorbents for the treatment of wastewater containing pollutant species from different industries and may help other applications in the design of MAmCS polymeric materials.
