Abstract
Foams based on micro and nanofibrillated cellulose, subjected to the oxidation process, and combined with natural rubber latex are revealed, as well as their production process, which involves mixing, freezing and freeze-drying steps. Foams have high porosity, structural resilience in liquid media and high adsorption capacity for organic compounds (such as dyes and detergents) and inorganic heavy metal compounds, not showing ecotoxicity and can be applied to remediate environments contaminated by these compounds.
