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