Abstract

The invention discloses a graphene cement base material capable of adsorbing heavy metal ions and a preparation method of the graphene cement base material, belonging to the technical field of composite materials. Used raw materials are functionalized graphene, cement, sand and water. The preparation method comprises the steps of adding the weighed functionalized graphene into the water, ultrasonically treating for 30min, adding the cement and the sand into a stirring pot, and stirring; then performing die-filling forming and maintaining to obtain a formed finished product of the graphene cement base material. The graphene cement base material has high capability of adsorbing the heavy metal ions in polluted water, can be used in places such as drainage pipelines, channels, artificial river-bed bottoms and sewage settling tanks, can be recycled, and is green and environment-friendly.

Description

technical field [0001] The invention discloses a graphene cement-based material for absorbing heavy metal ions and a preparation method thereof, belonging to the technical field of composite material preparation and application. Background technique [0002] With the acceleration of industrial development, the amount of heavy metal ions discharged into natural water bodies through wastewater is increasing. Heavy metal ions are easy to accumulate in water sources and soil. Under the amplification of food chain organisms, they are doubled and then enter the human body, destroying proteins and enzymes in the human body, and causing great harm to the human body. In addition, heavy metals are difficult to degrade and exist in various forms, so how to effectively remove heavy metal ions is an urgent problem in the current environmental problems. Adsorption is an appropriate method to deal with heavy metal ions because of its simple operation, low cost and good selectivity. Graph...
