STUDY ON THE CONDITIONS OF GRAPHENE DISPERSION ON MELAMINE FOAM TO PRODUCE OIL SORBENT

Abstract

Oil-sorbent is more effective to solve the oil pollution problems. This study aims of optimizing graphene dispersion condition on melamine sponge, thereby successfully fabricating oil-sorbent with high oil adsorption efficiency. The results showed that ethanol has the best ability to disperse graphene on melamine foam, reaching about 80% material weight; xylene is the lowest, reaching 20-27% material weight. However, oil and organic solvents adsorption capacity is highest with 15 minutes ultrasound in xylene. The adsorption capacity of gasoline, diesel and lubricants is up to about 75-80 times the initial weight of graphene sponge, especially 140 times for cooking oil.
