Abstract

This invention relates to a nano-gold-copper-zinc alloy bactericidal material, the main components of which are nano-gold particles, copper, and zinc; which are heated, dissolved, mixed, solidified, and plated in proportion to form an alloy material. It is suitable for water, reclaimed water, and sewage, and is especially suitable for the sterilization and disinfection of water that is closely related to people's lives. It has the following advantages: (1) It has a significant bactericidal effect and a broad antibacterial spectrum. According to the test, this material can kill 99.99% of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Aspergillus niger, and Candida albicans by passing a large dose of bacterial solution through water. (2) This material is non-toxic, harmless, non-irritating, non-corrosive, has a long action time, can be reused, and is green and environmentally friendly. (3) It has stable chemical properties and its bactericidal effect remains unchanged after being placed at room temperature for more than five years. (4) It has a wide range of uses, especially in fields closely related to people's health and life.
