To solve the problems of address oil spillage and organic pollutant, a series of magnetic ZIF-8/graphene aerogels (GA/NiFe2O4/ZIF-8) with different composite ratios were prepared by chemical reduction method. The composite aerogels were obtained by using NiFe2O4 as magnetic carrier, graphene (GO) as aerogel framework, and ZIF-8 as metal-organic material. The adsorptions of GA/NiFe2O4/ZIF-8 for ethanol, n-hexane, oleic acid, peanut oil and vacuum pump oil were investigated. The results show that the composite aerogels have high adsorption capacity (up to 20.0~46.6 times of their own mass). Compared with the control group, the adsorption capacities of composite aerogels for five types of organic solvents and oil are greater than that of pure graphene aerogel (GA) and magnetic graphene aerogel (GA/NiFe2O4). The cycle regeneration experiments of the obtained aerogels with different composite ratios were further carried out with n-hexane as target contaminant. After five cycles, the decreases of adsorption amount are not obvious, and the decreases are 1%~6%. Moreover, the efficient adsorption stability of GA/NiFe2O4/ZIF-8 at ﹣60~140 oC was investigated by using vacuum pump oil as target contaminant. The excellent properties of GA/NiFe2O4/ZIF-8 are expected to provide reference for oil-water separation.
