Green synthesis of immobilized hybrid biocomposite from natural waste for dye sequestration: a kinetic and isothermal approach

Key Points

• The aim is to develop an effective biocomposite for dye sequestration from wastewater using natural waste materials.
• Developed a hybrid biocomposite using natural waste through green synthesis methods.
• Evaluated the performance of the biocomposite in removing dyes across multiple cycles.
• Characterized the adsorption behavior using Langmuir and Vieth-Sladek models.
• The biocomposite showed strong dye removal performance over six cycles.
• Adsorption behavior was dominated by Langmuir kinetics, indicating a monolayer adsorption on the surface.
• The GS@NAB surface demonstrated structurally diverse domains from its composite materials.
