Post-Consumer Polyurethane Foams Hydrophobization Through Surface Modifications for Oil Spill Sorption

To increase oil sorption, polyurethane foams were modified with MoS2, ZnO grafting and/or hexadecanoic acid coating. The characterized by Scanning Electron Microscopy + Energy Dispersive X-ray Spectroscopy and Contact Angle techniques. Three sorption tests performed. In 100% water, the ZnO-PC modification showed a reduction of 35.7% in seawater when compared to Un-PC. oil, there was 29-fold (more than 2803%) S46 lubricant Un-PC performance ZnO-PC. on multicomponent systems, lowest 0.01 ± 0.00 g.g-1 (HA-PC), 0.08 (Un-PC), 1.39 0.02 (Un-PC) for 20W40 engine lubricating diesel, respectively. highest systems 41.34 1.02 32.81 0.31 (MoS2-PC), 14.78 0.27 (ZnO-PC) reuse indicated that even after 10 cycles, foam kept its capacity unchanged. Post-consumer proved be effective different oils spilled into seawater, especially those grafted rods or impregnated MoS2.
