摘　　要： 　　OWING TO THE SEVERE ENVIRONMENTAL AND ECOLOGICAL ISSUES ARISING FROM OIL SPILLS AND TOXIC CHEMICAL LEAKAGE, THE SEPARATION OF OIL FROM WATER PRESENTS A WORLDWIDE CHALLENGE TO SAVE THE ENDANGERED ENVIRONMENT.A VERSATILE ABSORBENT WHICH CAN DEAL WITH DIFFERENT TYPES OF OIL CONTAMINANTS IS IN HIGH DEMANDED FOR THIS ISSUE.[1-4] IN THIS WORK, WE OBTAIN AN ULTRALIGHT,FIRE-RESISTANT, AND COMPRESSIBLE FOAM IN A LARGE SCALE BY DIRECTLY COMBUSTION TREATMENT USING COMMERCIALLY AVAILABLE POLY(MELAMINE FORMALDEHYDE) FOAMS AS PRECURSORS.THE OBTAINED FOAM NOT ONLY EFFECTIVELY SEPARATES OILS FROM WATER AS EXPECTED, BUT ALSO POSSESSES A VERY HIGH ABSORPTION CAPACITY FOR THE REMOVAL OF OILS FROM WATER UP TO 145 TIMES ITS OWN WEIGHT.MORE IMPORTANTLY, DUE TO ITS FIRE-RESISTANCE AND COMPRESSIBILITY, DISTILLATION, COMBUSTION AND SQUEEZING, OR A COMBINATION OF THESE CAN BE APPLIED FOR RECYCLING THE FOAMS DEPENDING ON THE TYPE OF POLLUTANTS, MAKING THEM VERSATILE AND COMPREHENSIVE ABSORBENTS TO SATISFY VARIOUS PRACTICAL SEPARATION REQUIREMENTS.
