Effect of Structural Modification of Polyurethane Foam by Activated Carbon on the Adsorption of Oil Contaminants from Water
This study investigates both the capacity of pure polyurethane foam in adsorbing oil contaminants and the effect of its structural modification by activated carbon (composite) on the performance of the foam in terms of adsorption capacity and efficiency. To this end, pure polyurethane foam and its a...
