Our group has published new results on the use of TEMPO-oxidised cellulose nanofibrils for selective heavy metal ion removal from contaminated water streams.
The study, published in Advanced Sustainable Systems, demonstrates that surface-charged nanocellulose membranes can selectively capture Cu²⁺, Pb²⁺, and Cd²⁺ ions with efficiencies exceeding 95% at environmentally relevant concentrations.
This work was carried out in collaboration with the Department of Environmental Science at Stockholm University.
