Problems solved by technology

The disadvantage of this invention is that the introduction of metal sources as compounds of these metals such as silver nitrate, copper sulfate, etc. will easily carry a large amount of harmful anions in the porous material. When this water purification material is used to purify water, it will make the purification NO in water after 3 -1 , SO 4 -2 Plasma solubility is greatly increased, making the purified water worse

Abstract

The invention discloses a copper zinc alloy metal nano-filtration membrane and a preparation method thereof, and relates to a novel water purification material. The copper zinc alloy metal nano-filtration membrane comprises the following components: 40 to 50 percent of copper and 50 to 60 percent of zinc, or 80 to 90 percent of copper and 20 to 10 percent of zinc. The preparation method comprisesthe following steps of: putting a base material into physical vapor deposition vacuum equipment, vacuumizing, and cleaning and activating the base material; and performing physical vapor deposition on the base material, and plating the copper zinc alloy nano-filtration membrane on the base material. The nano-filtration membrane has the functions of bacteria resistance, chlorine removal and the like, has no ions of NO3<-1>, SO4<-2> and the like, and does not cause secondary pollution to water; and the nano-filtration membrane has high efficiency of removing residual chlorine and harmful heavy metal ions such as lead ions, mercury ions, hexavalent chromium, arsenic ions and the like in water, and has good effect. The removal rate of the residual chlorine reaches over 95 percent; the removalrates of the heavy metal ions Pb<2+>, Hg<2+>, Cd<2+>, Cr<6+> and As<5+> reach over 99 percent; and the antibacterial rate reaches over 99.99 percent. The production process is environment-friendly, and no waste water is drained.

Description

Technical field [0001] The invention relates to a new type of water purification material, in particular to a copper-zinc alloy metal nanofiltration membrane and a preparation method thereof. Background technique [0002] With the development of society and the improvement of living standards, people have higher and higher requirements for the quality of life. The impact of clean and safe drinking water on people's quality of life cannot be ignored. Water is the main carrier for the spread of various germs, and 80% of human diseases are related to water pollution. Obtaining clean and safe drinking water has become a hot topic worldwide. On the other hand, water pollution is becoming more and more serious. Surface waters such as rivers and lakes and groundwater in some areas are polluted to varying degrees. The water shortage problem of water quality has caused widespread concern. [0003] The main pollutants in drinking water are soluble heavy metal ions, arsenic ions, trace orga...
