| Physical and Chemical Properties | A chemically unstable blue gas with a pungent odor. It is a strong oxidant that can be decomposed into oxygen at any temperature. The food is decomposed and volatilized without leaving marks after treatment. |
| Use | Purposes: antimicrobial agents; Directly used as a disinfectant of water; Wastewater treatment agent. FDA approved in June 2001 for meat, poultry raw material handling, storage and processing, and the preparation, packaging and storage of primary agricultural products. |

TROPOSPHERICOZONE - Uses and synthesis methods
identification test
take cedar 3R124.5mg and disperse it in 500ml water in a 1L volumetric flask, and mix it mechanically overnight. Add 20mg of sodium hexametaphosphate, 48.5g of ammonium chloride and 6.2ml of ammonium hydroxide (equivalent to 1.6g of ammonia). Stir overnight after constant volume with water. After dilution to 10 times, the absorbance of the solution at 548nm is 0.155cm-1. The pH of the diluent of this reagent solution and sample water should be 8.1~8.50.
take 20ml of each of the above reagent solutions and put them into two 200ml volumetric flasks. Take ozone-free water and fix one of them as a blank. The other volumetric flask uses a directly manufactured sample to be sent below the reagent liquid level through a safety funnel or pipette to avoid ozone degassing loss. The absorbance of the two solutions at 548nm should be measured immediately with a 1 ~ 5cm absorption cell, and the absorbance of the sample should be lower than that of the blank sample.
content analysis 500ml of water and lml of phosphoric acid in a 1L volumetric flask, 0.770g of indigo trisulfonate potassium was added, and mixed with water for constant volume. The absorbance of the 1:100 diluent of the liquid at 600nm is 0.20±0.010. This is "spare indigo liquid". Before use, take 20ml of the spare liquid, 10g of sodium dihydrogen phosphate and 7ml of phosphoric acid and put them in a 1L volumetric flask, and mix them after constant volume with water, which is "indigo test solution I". In addition, it is the same as "indigo test solution I", but 100ml of "spare indigo solution" is used instead of 20ml, which is "indigo test solution II".
another 5g of malonic acid is diluted to 100ml as "malonic acid test solution".
add 10.0ml of "indigo test solution I" to each of the two 100ml flasks. One of them is filled with ozone-free water as a blank. The other volumetric flask uses a directly manufactured sample (ozone concentration should be 0.01~0.1mg/L) to be sent below the reagent liquid level through a safety funnel or pipette to avoid ozone degassing loss. Immediately mix and immediately use a 10cm absorption cell to measure the absorbance of the two solutions at 600nm (if the ozone concentration is 0.05~0.5mg/L, use "indigo test solution II" instead).
if chlorine exists in control interference, add lml of malonic acid test solution to each of the two flasks before adding the sample. The operation is the same as above, but the absorbance should be determined immediately.
Ozone concentration (mg/L) is calculated according to the following formula:
where D-the difference in absorbance between the sample liquid and the blank liquid;
6-range length, cm;
V-sample volume, ml (about 90 m1); F = 0.42.
use limited
FDA,& sect;:184.1563(2000): bottled water 0.4mg/L air 0.1 mg/kg(0.2 g/m).).
production method
The oxygen in the air is irradiated with ultraviolet rays on the spot, or the air is discharged through high voltage.
