Problems solved by technology

Generally, it is difficult to expose graphene at the gas-solid interface by composite granulation of graphene and other materials, and most of the graphene will be buried in the solid phase of the composite material, unable to exert the adsorption effect of high specific surface
For example: the porous ceramsite prepared by mixing graphene with bentonite, liquid paraffin, and sludge, most of the graphene will be completely submerged in the solid phase of the ceramsite, and it is difficult to have ceramsite at the porous gas-solid interface. Graphene is exposed, so the high specific surface properties of graphene cannot effectively play the role of adsorption

Abstract

The invention discloses a novel efficient water purification material and a preparation method thereof. The method includes the steps: constructing graphene holes; preparing multi-stage secondary pore ceramic substrate particles; preparing oxide nano particles on the ceramic substrate particles and the like. According to the water purification material prepared by the method, heavy metal ions in water are removed to form a relatively stable structure by the aid of synergistic effects of multi-stage secondary pore ceramic substrates, oxide nano particles in the substrates and graphene synergistic effect and synergistic actions of physical adsorption and chemical reaction. The material is high in voidage, large in specific surface area, high in adsorption capacity, high in efficiency, environmentally friendly and low in cost, can be used for water treatment and can almost completely remove various harmful heavy metals in water such as nickel, lead, arsenic, mercury, manganese, cadmium and chromium.

Description

technical field [0001] The invention belongs to the technical field of heavy metal water purification, and relates to a preparation method of a novel high-efficiency water purification material for removing nickel, chromium, arsenic and other heavy metals, in particular to a novel high-efficiency water purification material for industrial wastewater treatment and a preparation method thereof. Background technique [0002] In the field of environment and human health, heavy metals mainly refer to mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr), arsenic (As), manganese (Mn), copper (Cu), zinc (Zn), cobalt (Co), nickel (Ni) and other heavy metals. With the development of my country's economy and society, the shortage of water resources and water pollution are becoming more and more serious. Heavy metals are one of the main pollutants in the water environment. Relevant statistics show that my country's metal wastewater accounts for about 10% of the total wastewater dischar...
