Abstract

The application discloses a water-treated potassium ferrate sterilizing agent and a preparation method thereof. The water-treated potassium ferrate sterilizing agent is prepared by weighing and uniformly mixing potassium permanganate, concentrated hydrochloric acid, potassium hydroxide, iron nitrate nonahydrate, manganese dioxide, potassium chlorate, a polymerization inhibitor, triethylene tetramine, formaldehyde, phosphorus trichloride, a dispersing agent, sodium hydroxide, phosphorous acid, glycine and polyaspartic acid according to parts by weight. The melting point of the product is 205 DEG C; the scale inhibition rate is 96.9-98.9%; the sterilizing rate to escherichia coli, staphylococcus aureus, candida albicans, neisseria gonorrhoeae, penicillium, aspergillus, saprophytic bacteria and salmonella is 99-100%; when the water-treated potassium ferrate sterilizing agent is placed at 50-60 DEG C for a month, the sterilizing rate is 97.5-99.5%; when the water-treated potassium ferrate sterilizing agent is placed at 40-50 DEG C for half a year, the sterilizing rate is 96-99%; when the water-treated potassium ferrate sterilizing agent is placed at the room temperature for 1-2 years, the sterilizing rate is 95-97%.

Description

technical field [0001] The application belongs to the field of environmental protection reagent technology, and in particular relates to a potassium ferrate bactericide for water treatment with low cost and remarkable bactericidal effect and a preparation method thereof. Background technique [0002] Water treatment bactericide is also called bactericide and algicide, sludge stripper or anti-sludge agent. A class of chemicals that can inhibit the growth of bacteria, algae and microorganisms in manganese dioxide to prevent the formation of microbial slime and cause harm to the system. Including oxidizing fungicides, such as chlorine, sodium hypochlorite, bleaching powder, ozone, chloramine, etc.; non-oxidizing fungicides, such as dodecyl dimethyl benzyl ammonium chloride, dodecyl dimethyl benzyl bromide Ammonium, dithiocyanomethane, etc.; heavy metal compounds, such as mercuric oxide, mercuric chloride, mercuric fluoride, etc.; slime fungicides, such as rosin amine, hydrogen...
