A nanosilver antibacterial aromatic is consistently used in group feeding places, schools and toilets, is harmless to the human body, provides strong antibacterial, sterilizing and deodorizing effects, and emits natural incense. A nanosilver antibacterial aromatic comprises a silver colloidal solution, an aromatic solution, and a natural incense. The silver colloidal solution is prepared by agitating 200 ml of a silver colloid and 5 ml of hydrogen peroxide having a concentration of 35,000 ppm. The aromatic solution is prepared by agitating 600 ml of purified water and 400 ml of ethanol. The silver colloid is prepared by dissolving a silver salt into 100 ml of purified water, agitating 10 g of ferric oxide(Fe2O3) and the silver salt-dissolved solution for about one hour, filtering the mixed solution, diluting the filtered material with 200 ml of ethanol. The silver salt is prepared by injecting 100 g of silver into a dissolution tank, adding 100 g of nitric acid in the dissolution tank, heating the dissolution tank to dissolve silver with nitric acid, and simultaneously slowly adding 500 g of potassium carbonate(K2CO3) into the silver-dissolved solution and agitating the silver-dissolved solution and potassium carbonate. |
