Cross-Linking in Keratin-Based Films Enhances Cationic and Anionic Dye Adsorption.

ABSTRACT: Environmental concerns have increased with industrialization, and the growing demand for dyes has seen an exponential rise across industries like textile, leather, printing, etc. Most of the dyes are extremely toxic to the environment and thus affect both marine and terrestrial life. Sustainable dye removal technologies are, therefore, an urgent need. Most of the adsorbents selectively adsorb either cationic or anionic dyes, limiting their applicability. A simple yet effective approach is being reported to develop chemically cross-linked films from waste protein (human hair keratin) for both cationic and anionic dye adsorption. Keratin-based bioplastic films have been fabricated using waste human hair, and a comparative study with pristine keratin films was conducted. The cross-linked film
