Orange waste: A valuable carbohydrate source for the development of beads with enhanced adsorption properties for cationic dyes.

Eco-friendly pectin and pectin/cellulose microfibers beads (PB and PB-CF) were synthesized using compounds extracted from orange bagasse, a solid waste from the food industry. PB-CF beads showed remarkable differences regarding several properties as compared to the beads without CF. The adsorption capability of PB and PB-CF was tested towards the removal of methylene blue (MB) from aqueous solution.
