Highly efficient methyl blue dye adsorption by chitosan-gelatin-poly-l-lysine composite sponges with one-pot preparation: Characterization, adsorption performance, and DFT study

Key Points

• Composite sponges show exceptional adsorption performance for methyl blue, with capacity to remove 95% of the dye.
• Key metrics include a rapid adsorption rate of 0.29 mg/g·min, achieved through an innovative one-pot preparation method.
• Characterization techniques like DFT study underline the stability and efficiency of the sponges in dye removal.
• These findings highlight potential applications in wastewater treatment, supporting environmental sustainability.
