The invention discloses graphene oxide modified filter paper for oil-water separation and a preparation method thereof. By using a dip-coating method, filter paper is dipped into a graphene oxide solution for ultrasonic dispersion, and then taken out for natural drying at a room temperature, so that the graphene oxide modified filter paper for oil-water separation is obtained. The preparation method disclosed by the invention is simple, and low in cost; and the prepared filter paper is good in stability, has a good separation effect on an oil-water mixture, and has wide application prospects in rapid oil-water separation and oily wastewater treatment. 本发明公开了种氧化石墨烯改性油水分离滤纸及其制备方法，是采用浸涂法，将滤纸浸渍于氧化石墨烯溶液中，超声分散，然后取出，置室温下自然晾干，即得氧化石墨烯改性油水分离滤纸。本发明公开的制备方法简单、成本低、制得的滤纸稳定性好，对油水混合物具有良好的分离效果，在油水快速分离及含油废水处理中的应用前景广阔。
