Abstract

The invention discloses a formula for fast measuring ozone in water and a method thereof. The method comprises the following steps of: (1) preparing measuring reagent, respectively weighing 755 parts of sodium dihydrogen phosphate fine powder and 1 part of acid indigo carmine fine powder according to weight ratio, evenly mixing in a mixing cylinder, and sealing and packing according to 0.1g of each bag for later use; (2) firstly performing colorimetric measurement to water sample, adding 12.5mL of water sample to be measured into a cuvette with the diameter of 30mm, adding a bag of the measuring reagent prepared in the step (1) and evenly shaking, taking distilled water as reference, and measuring the absorbency under the condition that the wavelength is 600nm; (3) performing the colorimetric measurement to the water sample again, adding 12.5mL of the water sample to be measured into a measuring reagent and water sample-containing colorimetric bottle in the previous step again and evenly shaking, and measuring the absorbency under the condition that the wavelength is 600nm; and (4) computing the content of the ozone in the water with the formula p=1.071*(A1-2A2) / (0.42*3), wherein p is the concentration (mg / l) of the ozone in the water, A1 is the absorbency measured by the step (2), and the A2 is the absorbency measured by the step (3). The invention has the advantages of being simple in measurement steps, being capable of realizing on-site measurement with an automatic apparatus, and being low in measuring cost.

Description

technical field [0001] The invention relates to an environment monitoring method and an instrument, in particular to a method and an instrument capable of quickly measuring the ozone content in water. Background technique [0002] A small amount of ozone can play a role in disinfection and sterilization, making people feel refreshed and excited. It can also be used in industry to treat waste water containing polycyclic aromatic hydrocarbons and unsaturated hydrocarbon compounds such as polychlorinated biphenyls, phenol, naphthalene, etc., which are not easy to degrade , It can also be used as a decolorizer for diazo, azo and other dyes, and as a purifier for advanced treatment of drinking water and sewage with ozone activated carbon. However, because ozone has high chemical reactivity and strong irritation, it is harmful to human health. It mainly stimulates and damages the deep respiratory tract, and can damage the central system, and has a mild stimulating effect on the e...
