Removal of Methylene Blue Dye from Aqueous Solution Using Trichlorovinylsilane Chitosan–g–polyacrylamide Hydrogel

A new hydrogel based on vinylsilane-chitosan and acrylamide was synthesized as VSi-CTS-g-PAAm used to remove methylene blue (MB) from aqueous solution using batch adsorption technique. The VSi-CTS-PAAm interacted with dye at different mass-liquid ratios, pH, temperature. amount of MB removal estimated a UV-Vis spectrophotometer an optical density λmax= 665 nm. most effective pH 12, about 98 % 50 °C. study's findings also indicated that the equilibrium data exhibited highest degree conformity Langmuir isotherm model. Additionally, process adhered pseudo-second-order kinetics characterized endothermic. Therefore, our study suggests utilization prepared materials may have potential advantages in treating wastewater containing dyes.
