Preparation of Al3+ crosslinked PVA/Gelatin composite aerogel and its adsorption properties for acid dyes

Key Points

• The aerogel exhibits significant adsorption properties for acid dyes, enhancing material application.
• Adsorption effectiveness peaked with Al3+ crosslinked structures, capturing a notable percentage of dyes.
• Preparation involved synthesizing a polyvinyl alcohol and gelatin composite aerogel with Al3+ crosslinking agents.
• Indicates potential for environmental applications in dye removal processes, suggesting further exploration is needed.
