Embodiment 1

[0012] The air disinfectant (% by weight) consists of 0.02 papaya seed extract, 0.05 sodium carboxymethylcellulose, 0.02 EDTA, and 99.91 water. Wherein, the preparation method of papaya seed extract is as follows: papaya seeds are shelled, ground, add 10 times of volume containing 5% NaCl, the phosphate buffer of pH6.8 is fully ground in homogenizer, supernatant after centrifugation Separation by CM-Celluse 32 cation exchange column chromatography, eluting with 0.4M NaCl (pH5.2), 0.05M acetic acid buffer, and then using 0.4-0.8M NaCl (pH5.2), 0.05M acetic acid buffer for continuous ionization Concentration gradient elution is performed, and the protein-containing eluate is vacuum-dried to obtain papaya seed extract.

[0013] Determine the number of spraying points according to the room area, less than 20m 2 Set 6 points, every increase of 10m 2 Add 3 points, each point is sprayed 3 times with a sprayer in an arc shape, and after 15 minutes of spraying, the number of colonies...

Embodiment 2

[0015] This air disinfectant (weight %) is made up of 0.02 papaya seed extract, 0.05 sodium carboxymethyl cellulose, 0.03EDTA, 99.9% water, tests according to the spraying method of embodiment one, and the results are shown in Table 1.

Embodiment 3

[0017] This air disinfectant (weight %) is made up of 0.12 papaya seed extract, 0.10 sodium carboxymethyl cellulose, 0.03EDTA, 99.75 water, tests according to the spraying method of embodiment one, and the results are shown in Table 1.

Abstract

An indoor air disinfectant without environmental pollution is proportionally prepared from the extract of papaya seed, carboxymethyl cellulose sodium, EDTA and water.

Description

technical field [0001] The present invention relates to a preparation for disinfecting indoor air. Background technique [0002] The cleanliness of the air directly affects human health. With the development of society, economy, and transportation, the density and mobility of the social population have increased, and the opportunities for people to communicate and gather have increased. Therefore, the resulting air pollution hazards in the working and living environments have attracted increasing attention. Moreover, the incidence of airborne diseases has remained high in recent years, making the solution to the problem of air disinfection more urgent. [0003] There are a variety of air disinfectant research reports and products, but most air disinfectants use chemical disinfectants, which have problems such as irritation, corrosion and toxicity; some air disinfectants use traditional Chinese medicine preparations, and there are also complex formulas, which are inconvenien...
