Nowadays, adsorption is recognized as one of the major significant separation processesamid the physical, biological, and chemical processes.Activated carbon adsorption has been widely used for the purification of water andwastewater and for the treatment of numerous environmental problems. In this work,polyurethane (PU) foam-activated carbon composites were synthesized, by mixing of a numberof well-defined ingredients such as, polyol and toluene diisocyanate, to produce a flexible foamof alveolar structure after polymerization reactions, and were characterized by several techniquessuch as Scanning Electron Microscopy (SEM), wettability analysis, Density ( geometricmeasurement and measured by the Archimedes principle), Porosity, spectroscopic analysis(Infrared and Raman) and mechanical analysis (compression - decompression cycle).The synthesized composite was used to remove crude oil, which is a source ofenvironmental issues. The prepared monolith enabled the recovery of 96% of sorbed crude oilfrom the sorbent material by simple compressive force. This will allow repetitive use of thespongy material thus prepared, which may be very helpful for local economies. The use of amodel whose validity attained 0.81 helped us avoid tedious and costly experiments, by using thedesign of experiments method.
