IN370456: Sustainable biomaterial nanocomposites for water treatment in tea-bag-like pouches and process for preparation thereof

Invention discloses a sustainable Biomaterial Scaffold (BMS) nanocomposites useful for removal of Fluoride, reactive Black and Cr(VI) for water purification and process for the preparation of Biomaterial Scaffold (BMS) nanocomposites. Its application in removal of fluoride (F-), chromium (Cr(VI)) and color contaminants from water is reported. This BMS nanocomposite exhibited as high as ~168 mg g-1 and ~60 mg g-1 fluoride uptake efficiency at pH 4 and pH 7 respectively, and ~8.5 mg g-1 Cr(VI) uptake capacity. With this material, >99 % reactive black-5 (RB-5) removal was achieved with remarkable surface regeneration property.
