Abstract
The present disclosure provides cellulose/metal composites and their use in removing impurities from liquids, including water. Carboxylated nanocelluloses are combined with metal ions and the resulting composite may be contacted with a liquid, including water, to remove impurities therefrom.
Claims8
A method comprising:
- contacting at least one carboxylated cellulose nanofiber with at least one positively charged metal ion to generate a composite;
- and
- contacting the composite with a liquid to remove negatively charged impurities from the liquid.
Dependencies are inferred from the claim text.
