Preparation of sustainable nanocomposite as new adsorbent for dyes removal

Sustainable nanocomposite from chitosan, silk fibroin and hydroxyapatite was investigated as adsorbent for organic dyes removal from waste water. Chitosan/silk fibroin bioactive blend initiated successfully the mineralization of hydroxyapatite rod-like crystals with ~40 nm diameter. The formed nanocomposite was applied for methylene blue (MB) removal from waste water. The adsorption kinetics were fitted with Pseudo-second order kinetic model. Adsorption results well fitted to the Langmuir model and showed maximum adsorption capacity 476 mg/g. The current nanocomposite is sustainable and efficient adsorbent for organic dyes removal from waste water.
