▎ 摘 要
NOVELTY - A superhydrophobic reduction graphene oxide/sponge composite material is prepared by soaking sponge into anhydrous ethanol, ultrasonically cleaning, taking out, water washing, drying, dissolving graphene oxide into water, ultrasonically dispersing to obtain graphene oxide solution, adding ethylene diamine, transferring into microwave-ultrasonic wave reactor, regulating microwave and ultrasonic wave power, boiling to reflux, reacting, adding pre-treated sponge, continuously reacting, taking out sponge, water washing, and drying. USE - Method for preparing superhydrophobic reduction graphene oxide/sponge composite material (claimed) used as selective adsorbent for oil-containing waste water processing. ADVANTAGE - The material has large adsorption amount, good stability, and excellent hydrophobic property and oil suction performance. The method is good for industrial large scale production, and has simple operation, low cost, short reaction time, high efficiency and low consumption.
