Abstract

Abstract

Municipal sludge is rich in organic matter,which can provide carbon source for the preparation of graphene oxide (GO).In this paper,GO was prepared from municipal sludge by modified Hummers method.Response surface methodology (RSM) was used to optimize GO preparation conditions,including toner dosage,potassium permanganate dosage,concentrated sulfuric acid dosage,and ultrasonic time,based on single factor experiment.The optimized preparation conditions of GO-based on municipal sludge were carbon powder of 3.22 g,potassium permanganate of 4.12 g,concentrated sulfuric acid of 22.63 mL and ultrasonic time of 7.61 h.Scanning electron microscopy and infrared spectroscopy analysis showed that GO prepared under the optimum experimental conditions had obvious lamellar structure,with O-H (hydroxyl) characteristic peaks at about 3400 cm^-1 and 1400 cm^-1,C=O (carbonyl) characteristic peaks at about 1700 cm^-1,and C-O (epoxy) characteristic peaks at about 1200 cm^-1.It was consistent with the properties of GO prepared with the traditional materials.Thus,a new direction and theoretical basis were provided for the utilization of municipal sludge by preparing GO.
