Abstract

The invention provides a Cu-Zn-ZnO composite material and a preparation method and application thereof, and relates to the technical field of water body purification materials. According to the composite material, a zinc oxide one-dimensional nano material is directly grown on the surface of a copper-zinc alloy, and the composite material is prepared from the following elements in percentage by weight: 49-89% of Cu, 9-42% of Zn and 2-9% of O. The preparation method of the composite material comprises the step that the composite material is obtained by hydrothermal synthesis of the copper-zincalloy in a high-pressure digestion tank. The composite material can be used in a purification and sterilization device of a washing machine, a water heater or a water purifier. The novel composite material of which the zinc oxide one-dimensional nano material is directly grown on the surface of the copper-zinc alloy is synthesized in one step by a hydrothermal method by using the copper-zinc alloyas a raw material. The composite material not only has the function of removing residual chlorine, heavy metal ions and hydrogen sulfide, but also can effectively kill microorganisms such as bacteriaand viruses, the functions are comprehensive, and water bodies can be thoroughly purified.

Description

technical field [0001] The invention relates to the technical field of water purification materials, in particular to a Cu-Zn-ZnO composite material and its preparation method and application. Background technique [0002] In recent years, with the continuous development of my country's economy, environmental damage has become increasingly serious, especially the pollution of tap water. At present, the pollution of tap water is divided into three aspects: one is source pollution. According to the relevant statistics of the environmental department, 80% of the rivers in our country are polluted to varying degrees; in the domestic water system, nearly 40% of the rivers are not suitable for drinking. The source of water; nearly 80% of the river sections passing through the city are not suitable for drinking water sources; about half of the urban groundwater sources are polluted. The second is the pollution of the tap water transmission pipeline. The tap water from the company ...
