preparation example Construction

[0026] The invention proposes a preparation method of an extract degrading triphenyl and a triphenyl purifying agent, which are suitable for controlling indoor air pollution after decoration.

[0027] The present invention proposes a preparation method of an extract degrading triphenyl, the preparation method comprising the following steps:

[0028] Will be at 0.1mg / m 3 ~0.5mg / m 3 Poppins cultivated in benzene concentration environment for 30 to 60 days and at 0.15mg / m 3 ~0.65mg / m 3 Grinding the chrysanthemum chrysanthemum cultured for 60 days to 90 days in a toluene concentration environment to obtain a mixed grinding product;

[0029] With the ratio of the mass of the mixed grind to isopropanol being 1: (8-12), weigh the isopropanol and add it to the mixed grind, and obtain a filtrate after filtration.

[0030] Further, the specific steps of taking isopropanol and adding it into the mixed grind, and obtaining the filtrate after filtering include:

[0031] Weigh isopropa...

Abstract

The invention discloses a preparation method of a degraded triphenyl extract and a triphenyl scavenger. The preparation method of the degraded triphenyl extract comprises the following steps: 3 ~0.5mg / m 3 Poppins cultivated in benzene concentration environment for 30 to 60 days and at 0.15mg / m 3 ~0.65mg / m 3 Grind the chrysanthemum chrysanthemum cultivated in a toluene concentration environment for 60 to 90 days to obtain a mixed grind; the mass ratio of the mixed grind to isopropanol is 1: (8 to 12), and the isopropyl alcohol is weighed Alcohol and added to the mixed grind, mixed and filtered to obtain the filtrate. The technical scheme of the present invention realizes the decomposition of p-triphenyl substances through an extract that degrades triphenyl, so as to achieve the effect of purifying indoor air.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a preparation method of an extract degrading triphenyl and a triphenyl purifying agent. Background technique [0002] With increasing health awareness, indoor air quality has become the focus of attention. Since triphenyl (ie benzene, toluene and xylene) is used as a chemical raw material or solvent, it is widely present in various decorative materials. When the concentration of triphenyl substances in the room exceeds the standard, it can cause symptoms such as dizziness, nausea, and vomiting. If the human body is exposed to the triphenyl environment for a long time, it will cause serious and irreversible damage to the human respiratory system, nervous system and immune system. . [0003] Since triphenyl substances all have a stable benzene ring structure, their chemical properties are stable, and redox reactions are not easy to occur, and addition and substitution re...
